ap2161d/ap2171d document number: ds32250 rev. 5 - 2 10 of 19 www.diodes.com march 2013 ? diodes incorporated ap2161d/ap2171d application note the ap2161d and ap2171d are integrated high-side power switches optim ized for universal serial bus (usb) that require protectio n functions. the power switches are equipped with a driver that controls the gate voltage and incorporates slew-rate limitation. this, along with the various protection features and special functions, makes these power switches ideal for hot-swap or hot-plug applications. protection features: under-voltage lockout (uvlo) under-voltage lockout function (uvlo) guarantees that the internal power switch is initially off during start-up. the uvlo func tions only when the switch is enabled. even if the switch is enabled, the switch is not turned on until the power supply has reached at least 1.9v. whenever the input voltage falls below approximately 1.9v, the power switch is turned off. this facilitates the design of hot-insertion systems where it is not possible to turn off the power switch before input power is removed. over-current and short circuit protection an internal sensing fet is employed to c heck for over-current conditions. unlike curr ent-sense resistors, sense fets do not inc rease the series resistance of the current path. when an ove r-current condition is detected, the device maintains a constant output current and reduces the output voltage accordingly. complete shutdown occurs only if the fault stays long enough to activate thermal limiting. the different overload conditions and the correspondi ng response of the ap2161d/2171d are outlined below: s.no conditions explanation behavior of the ap2161d/2171d 1 short circuit condition at start-up output is shorted before input voltage is applied or before the part is enabled the ic senses the short circuit and immediately clamps output current to a certain safe level namely i limit. 2 short-circuit or over-current condition short-circuit or overload condition that occurs when the part is enabled. ? at the instance the overload occurs, higher current may flow for a very short period of time before the current limit function can react. ? after the current limit func tion has tripped (reached the over- current trip threshold), the device switches into current limiting mode and the current is clamped at i limit . 3 gradual increase from nominal operating current to i limit load increases gradually until the current-limit threshold.(i trig ) the current rises until i trig or thermal limit. once the threshold has been reached, the device switches into its current limiting mode and is set at i limit . note that when the output has been shorted to gnd at extremely low temperature (< -30 c), a minimum 120- f electrolytic capacitor on the output pin is recommended. a correct capacitor type with capac itor voltage rating and temperature characteristics must be prop erly chosen so that capacitance value does not drop too low at the extremely lo w temperature operation. a recommended capacitor should have t emperature characteristics of less than 10% variati on of capacitance change when operated at extr emely low temp. our recommended aluminum electrolytic capacitor type is panasonic fc series. thermal protection thermal protection prevents the ic from damage when the die temperat ure exceeds safe margins. this mainly occurs when heavy-ove rload or short-circuit faults are present for extended periods of time. the ap2161d/ap2171 d implements thermal sensing to monitor the op erating junction temperature of the power distribution switch. once the die temperature rises to approximately +140c, the thermal protection fe ature gets activated as follows: the internal thermal sense circuitry turns the power switch off and the flg output is asserted thus preve nting the power switch from damage. hysteresis in the thermal sense circuit allo ws the device to cool down to approximately +25c before the ou tput is turned back on. the built-in thermal hysteresis feature avoids undesirabl e oscillations of the thermal protection circuit. the switch continues to cycle in this manner until the load fault is removed, resulting in a pul sed output. the flg open-drain output is asserted when an over-c urrent occurs with 7-ms deglitch. reverse current protection in a normal mosfet switch, current can flow in reverse direct ion (from the output side to the input side) when the output side voltage is higher than the input side, even when the switch is turned off. a reve rse-current blocking feature is implemented in the ap21x1 series to prevent such back currents. this circuit is activated by the difference between the output voltage and the input voltage. when the switch is disabled, this feature blocks reverse current flow from the output back to the input.
ap2161d/ap2171d document number: ds32250 rev. 5 - 2 11 of 19 www.diodes.com march 2013 ? diodes incorporated ap2161d/ap2171d application note (cont.) special functions: discharge function when enable is de-asserted, the discharge func tion is active. the output capacitor is discharged through an internal nmos that has a discharge resistance of 100 ? . hence, the output voltage drops down to zero. the time taken for discharge is dependent on the rc time constant of the resistance and the output capacitor. flg response the flg open-drain output goes active low for any of the two condit ions: over-current or over-temperature. the time from when a fault condition is encountered to when the flg output goes low is 7-ms (typ). the flg output remains low until both over-current and over-temp erature conditions are removed. connecting a heavy c apacitive load to the output of the device can cause a momentary over-current condi tion, which does not trigger the flg due to the 7-ms deglitch timeout. the 7- ms timeout is also applicable fo r over-current recovery and th ermal recovery. the ap2161d/ap2171d are designed to eliminate erroneous over-current reporting without the need for external components, such a s an rc delay network. applications information: power supply considerations a 0.01- f to 0.1- f x7r or x5r ceramic bypass capacitor between in and gnd, close to the device, is recommended. this limits the input voltage drop during line transients. placing a high-va lue electrolytic capacit or on the input (10- f minimum) and output pin(s) is recommended when the output load is heavy. this precaution also reduces power-suppl y transients that may caus e ringing on the input. additi onally, bypassing the output with a 0.01- f to 0.1- f ceramic capacitor improves the immuni ty of the device to short-circuit trans ients. this capacitor also prevents output from going negative during turn-off due to inductive parasitics. power dissipation and junction temperature the low on-resistance of the internal mosfet allows the small surface-mount packages to pass large current. using the maximum o perating ambient temperature (t a ) and r ds(on) , the power dissipation can be calculated by: p d = r ds(on) i 2 the junction temperature can be calculated by: t j = p d x r ? ja + t a where: t a = ambient temperature c r ja = thermal resistance p d = total power dissipation generic hot-plug applications in many applications it may be necessary to remove modules or pc boards while the main unit is still operating. these are consi dered hot-plug applications. such implementations require the control of current surges as seen by the main power supply and the card being in serted. the most effective way to control these surges is to limit and slowly ramp up the current and voltage being applied to the card, similar to the way in which a power supply normally turns on. due to the controlled rise and fall times of the ap2161d/ap2171d, these devices can be used to provide a softer start-up to devices being hot-plugged into a powered system. the uv lo feature of the ap2161d/ap2171d also ensures that the swit ch is off after the card has been removed, and that the switch is off during the next insertion. by placing the ap2161d/ap2171d between the v cc input and the rest of the circuitry, the input po wer reaches these devices first after insertion. the typical rise time of the switch is approximately 1ms, providing a slow voltage ramp at the output of the device. this implementation controls the system surge current and provides a hot-plugging mechanism for any device.
