4 fn9252.2 july 28, 2010 pin description vin (pin 1, 15, 16 for isl9205; pin 1 for isl9205a, isl9205b, isl9205c and isl9205d) vin is the input power source. connect to a wall adapter. fault (pin 2) fault is an open-drain output indicating fault status. this pin is pulled to low under any fault condition. when a fault condition occurs, the time counter will be reset. when the charger is disabled, the fault pin outputs high impedance. status (pin 3) status is an open-drain output indicating charging and inhibit states. the status pin is pulled low when the charger is charging a battery. it will be turned into high impedance when the charge current drops to imin. this high impedance state will be latched until a recharge cycle or a new charge cycle starts. when the charger is disabled, the status pin outputs high impedance. time (pin 4) the time pin determines t he oscillation period by connecting a timing capacitor between this pin and gnd. the oscillator also provides a time reference for the charger. gnd (pin 5) gnd is the connection to system ground. toen (pin 6 for isl9205; n/a for isl9205a, isl9205b, isl9205c and isl9205d) toen is the timeout enable input pin. pulling this pin to low disables the timeout char ge-time limit for the fast charge modes. leaving this pin high or floating enables the timeout limit. there is an internal 400k pull-up resistor at this pin. en (pin 7 for isl9205; pin 6 for isl9205a, isl9205b, isl9205c and isl9205d) en is the enable logic input. connect the en pin to low to disable the charger or leave it floating to enable the charger. there is an internal 400k pull-up resistor at this pin. v2p8 (pin 8 for isl9205; pin 7 for isl9205a, isl9205b, isl9205c and isl9205d) this is a 2.8v reference voltage output. this pin provides a 2.8v voltage source when the input voltage is above the por threshold and outputs zero otherwise. the v2p8 pin can be used as an indication for adapter presence. iref (pin 9 for isl9205; pin 8 for isl9205a, isl9205b, isl9205c and isl9205d) this is the charge current programming and monitoring pin. connect a resistor between this pin and gnd to set the charge current during the constant current phase, as given by equation 1: where r iref is in k . imin (pin 10 for isl9 205; n/a for isl9205a, isl9205b, isl9205c and isl9205d) imin is the end-of-charge (eoc) current programming pin. connect a resistor between this pin and gnd to set the eoc current, as given by equation 2: where r imin is in k . temp (pin 11 for isl9205; pin 9 for isl9205d; n/a for isl9205a, isl9205b and isl9205c) temp is the input for an exte rnal ntc thermistor. the temp pin is also used for battery removal detection. vsen (pin 12 isl9205; pin 9 for isl9205a, isl9205b and isl9205; n/a for isl9205d) vsen is the remote voltage sens e pin. connect this pin as close to the battery positive terminal as possible. if the vsen pin is left floating, its volt age drops to zero volt and the charger operates in trickle mode. vbat (pin 13, 14 for isl9205; pin 10 for isl9205a, isl9205b, isl9205c and isl9205d) vbat is the connection to the battery. typically a 10 f tantalum capacitor is needed for stability when there is no battery attached. when a batt ery is attached, only a 0.1 f ceramic capacitor is required. i ref 80 r iref ----------------- a () = (eq. 1) i min 8000 r imin ---------------- ma () = (eq. 2) isl9205

9 fn9252.2 july 28, 2010 functional block diagram theory of operation the isl9205 is an integrated charger for single-cell li-ion or li-polymer batteries. the isl92 05 is capable of operating in two operation modes, linear charge mode and pulse charge mode. the isl9205 functions as a traditional linear charger when powered with a voltage source adapter. when powered with a current-limited ada pter, the charger functions as a pulse charger by fully turning on the pass element and the power dissipation is hence drastically reduced. constant current phase the isl9205 starts the charge at a constant current (cc) phase. the charge current is regulated to fast charge the battery before the final voltage has been reached. the charge current is programmable with the iref pin and has two operation modes: trickle mode and constant current mode, depending on the battery voltage. when the battery voltage is lower than 2.8v, the charger operates in trickle mode where the charge current is set at 10% of the constant current mode current. the trickle mode is for preconditioning a deeply discharged battery. once the battery voltage is above the typical 2.8v threshol d, the constant current (cc) mode starts. the constant current is programmable between 50ma to 1a. constant voltage phase when the battery reaches the final voltage, the isl9205 switches the operation to a co nstant voltage (cv) phase. the output voltage is regulated at the final voltage value. logic status i sen vin vbat 100000:1 current mirror counter + - + - v min + - + - v ch iref + - fault recharge minbat vrechrg ca va min_i ir i sen i min = ir/10 chrg status fault + - + - input_ok v por trickle/fast references v2p8 temperature monitoring current references it time osc gnd vin v ch v min v por vrechrg q main q sen r iref c1 vsen + 80mv - en input_ok esd diode temp monitor temp isl9205
10 fn9252.2 july 28, 2010 during the constant voltage phase, the charge current reduces gradually as the cell voltage rises. end-of-charge and recharge as the charge current reac hes the eoc (end-of-charge) current threshold during the constant voltage phase, the status pin open-drain fet is turned off to indicate an eoc condition. the eoc current is programmable for the isl9205 by connecting a resistor from the imin pin to gnd. for others, the eoc current is fixed at 10% of the programmed constant charge current. when the status pin indicates the eoc condition, the charger will continue to charge until the en pin is pul led to logic low or the input power has been removed. after eoc is reached, recharge will occur when the battery voltage falls to 150mv below the constant voltage value. the status open-drain fet is turned on when a recharge condition is met. an internal delay is implemented at the status pin for both eoc and recharge conditions to prevent nuisance trips due to noise and fast load current transitions. the delay time is approximately one clock cycle (varies betwe en 0.5 and 1.5 clock) of the internal oscillator, which is programmed by the timer capacitor. the typical charge waveforms in figure 13 show the complete cycle operation. temperature monitoring and thermal foldback in the event where the die temperature reaches the thermal foldback threshold (+110c typical), the charge current is reduced accordingly to prevent further temperature rise. in the isl9205 and isl9205d versions, there is an external temperature monitoring functi on. a negative temperature coefficient (ntc) thermistor can be connected between the temp pin and gnd to monitor the battery temperature or ambient temperature. the hyster esis comparators internal to the isl9205 provide a valid temperature window centered at the voltage of the temp pin, which is programmed by the ntc and the pull-up resistor conn ected to the pin. when the measured temperature is outsi de this window, the charger is paused (both the charger and the timer are stopped) and a fault indication is issued. if the thermistor is attached to the battery, the temp function can be used to discover a battery removal condition when the temp pin voltage is much higher than the reference threshold. por the power-on reset (por) func tion monitors the supply voltage. the por has a rising edge threshold of 3.6v typical and 2.5v typical for falling edge. the charger is expected to operate when the input voltage is above the por threshold. after por the charger will continue to operate for supply voltage down to 2.5v typical. it is also required that the supply voltage be higher than the vbat pin voltage by a typical 80mv for the charger to function. oscillator, timeout, and charge cycle the isl9205 incorporates with an oscillation circuit using an external timing capacitor connected to the time pin. the oscillator sets the limit for the maximum charge time during the trickle mode and the fast mode (cc and cv). the maximum charge time (timeout) for the fast mode is set by: timeout = 2 22 t osc where the t osc is the oscillator period. the minimum programmable t osc is 20 s (c time = 100pf). the time limit for the trickle charge is 1/8 of the fast mode time limit. in the isl9205, the time-out function can be disabled by pulling the toen pin to logic low. when timeout is disabled, the charger will never be turned off in constant current and constant voltage modes. for the isl9205b and the isl9105d, the timeout function is always enforced. for the isl9105a, there is not timeout function. a charge cycle is the time inte rval between the time when the charger is enabled to the moment it is disabled. if the battery voltage is lower than the trickle charge threshold at the time the charger is enabled, the charger enters the trickle mode and the timer is reset and its limit is set to 1/8 of timeout. if the timeout func tion is enabled, the charger will stop and indicate a timeout fault if the charge time is longer than the limit. if the trickle mode completes successfully before the time limit, the charger moves to cc mode and the timer is reset and the time limit is set to timeout. the charger needs to reach the eoc conditions before the timeout interval elapsed, otherwise, a timeout fault will be issued. the charger indicates the eoc with the status pin but does not terminate charging. disabling timeout with toen in the isl9205, the time-out f unction in fast charge state (cc/cv) can be disabled by pulling the toen pin to logic low. the timeout function for the trickle charge mode can not be disabled. note that in the isl9205a, there is no timeout function for both the trickle and the cc/cv intervals whereas in the isl9205 with toen set pulled to low, there is no timeout for the cc/cv inte rval but the timeout function for the trickle interval is still enforced. figure 13. typical charge cycle with timeout i ref trickle cc cv i min

11 fn9252.2 july 28, 2010 indications the isl9205 has two open-drain status indication pins. these two pins are fault and status . these pins require an external pull-up resistor to function properly. the v2p8 pin can be used as the presence of ac adapter. charger disable the en pin allows the user to disable the charger. when the charger is disabled, all internal circuits are shut down and the quiescent current at the input pin is less than a typical value of 150ma. remote battery voltage sensing in the isl9205 and the isl9205a, isl9205b and isl9205c versions, a kelvin sense pin is provided for battery terminal voltage monitoring. thus, the ir drop due to the connection leads and pcb traces can be eliminated, resulting a more accurate battery voltage monitoring, especially when the battery is located at a signif icant distance away from the isl9205. if remote sensing is not needed, the vsen pin can be connected to vbat at the ic. applications information pcb layout guidance the isl9205 uses a thermally-enhanced qfn/dfn packages that has an exposed thermal pad at the bottom side of the package. the layout should connect as much as possible to copper on the exposed pad. typically the component layer is more effective in dissipating heat. the thermal impedance can be further reduced by using other layers of copper connecting to the exposed pad through a thermal via array. a minimum of four (4) such thermal vias are recommended. each thermal via is recommended to have 0.3mm diameter and 0.7mm distance from other thermal vias. stability consideration the isl9205 should behave like a current and thermal limited linear regulator. the charger operation is stable with an output ceramic decoupling capacitor in the range of 1f to 200f, with or without a battery connected. input bypass capacitor due to the inductance of the power leads of the wall adapter or usb source, the input capacitor type must be properly selected to prevent high voltage transient during a hot-plug event. a tantalum capacitor is a good choice for its high esr, providing damping to the voltage transient. multi-layer ceramic capacitors, however, have a very low esr and hence when chosen as input capacitor, a 1 series resistor must be used, as shown in the ?typical applications? on page 3, to provide adequate damping. state machine diagram the state machine diagram is shown in figure 14. the diagram starts with the powe r-off state. when the input voltage rises above the por threshold, the charger resets itself. then, if the charger is disabled, the charger stays in the charger disabled state. if the charger is enabled, the trickle charge starts. anytime when entering the trickle charge state, the internal timeout timer is reset. there are two paths to exit the trickle charge, one is when the battery voltage rises above the preconditioning charge threshold within the 1/8 timeout interval and the other is when the 1/8 timeout interval has been elapsed before reaching the preconditioning charge voltage threshold. when timeout fault occurs, the charger enters the timeout fault state. there are only two ways to exit the timeout fault state, by toggling the en input or re-cycling the input power. if the charger finishes the trickle c harger before the 1/8 timeout limit, it moves to the fast charge state. when entering the fast charge state, the timeout timer is reset as well. if the charger hits eoc conditions before the timeout, the charger enters charge compete state. the charger stays on but the status indicates eoc condition. when vbat drops below the recharge threshold, the status pin will turn to logic low to indicate charging again. isl9205
