UP7534 4 upi semiconductor corp., http://www.upi-semi.com rev. f02, file name: UP7534-ds-f0200 power switch the power switch is an n-channel mosfet with a low on- state resistance. configured as a high-side switch, the power switch prevents current flow from vout to vin and vin to vout when disabled. the power switch is controlled by a logic enable input (active high for UP7534a/c/e/g and active low for UP7534b/d/f/h) and driven by an internal charge pump circuit. when the output load exceeds the current-limit threshold or a short is present, the UP7534 asserts overcurrent protection and limits the output current to a safe level by driving the power switch into saturation mode. charge pump an internal charge pump supplies power to the driver circuit and provides the necessary voltage to pull the gate of the mosfet above the source. the charge pump operates from input voltages as low as 2.7 v and requires little supply current. driver the driver controls the gate voltage of the power switch. to limit large current surges and reduce the associated electromagnetic interference (emi) produced, the driver incorporates circuitry that controls the rise times and fall times of the output voltage. chip enable (for UP7534a/c/e/g) the en pin receives a ttl or cmos compatible input to enable/disable the UP7534a/c/e/g logic low disables the power switch, charge pump, gate driver and other circuitry and reduces the supply current down to less than 1ua. logic high restores bias to the drive and control circuits and turns the switch on. chip enable (for UP7534b/d/f/h) the en# pin receives a ttl or cmos compatible input to enable/disable the UP7534b/d/f/h. logic high disables the power switch, charge pump, gate driver and other circuitry and reduces the supply current down to less than 1ua. logic low restores bias to the drive and control circuits and turns the switch on. soft start the UP7534 features soft start function to eliminate the inrush current into downstream and voltage droop of upstream when hot-plug-in with capacitive loads. the soft start interval is 0.9ms typically. the input current to charge up the load capacitor is proportional to its capacitance. the UP7534 current limit function may be active during the plug-in of extreme large capacitive load. the fault flag is masked during the softstart interval. over current limit the UP7534 continuous monitors the output current for overcurrent protection to protect the system power, the power switch, and the load from damage during output short circuit or soft start interval. when an overload or short circuit is encountered, the current-sense circuitry sends a control signal to the driver. the driver in turn reduces the gate voltage and drives the power fet into its saturation region, which switches the output into a constant-current mode and holds the current constant while varying the voltage on the load. the current limit level is typical 1a when the power switch operates in linear region and is typical 0.6a in saturation region (for UP7534a/bs8-06). the UP7534 asserts fault condition and pulls low oc# when overcurrent, overtemperature, input under voltage lockout condition is encountered. the output remains asserted until the overcurrent or overtemperature condition is removed. a 8ms deglitch circuit prevents the oc# signal from oscillation or false triggering. if an overtemperature shutdown occurs, the oc# is asserted instantaneously. overtemperature protection the UP7534 continuously monitor the operating temperature of the power switch for overtemperature protection. the UP7534 asserts overtemperature and turns off the power switch to prevent the device from damage if the junction temperature rises to approximately 135 o c due overcurrent or short-circuit conditions. hysteresis is built into the thermal sense, the switch will not turns back on until the device has cooled approximately 20 degrees. the open- drain false reporting output (oc#) is asserted (active low) when an overtemperature shutdown or overcurrent occurs. if the fault condition is not removed, the switch will pulse on and off as the temperature cycles between these limits. undervoltage lockout a voltage sense circuit monitors the input voltage. when the input voltage is below approximately 2.2v, a control signal turns off the power switch. output voltage discharge when disabled the output voltage is discharged through an internal 100 ? resistor when the output voltage is disabled. functional description www.datasheet.co.kr datasheet pdf - http://www..net/

UP7534 11 upi semiconductor corp., http://www.upi-semi.com rev. f02, file name: UP7534-ds-f0200 supply input filtering vin pins supply power to the power switch and internal circuit. both of them should be connect to upstrem power supply with short and wide trace on the pcb. events such as hot-plug/unplug, output short circuit and overtemperature result in step change of input current with sharp edges, which in turn causes voltage transient at supply input due to di/dit effect of parasitic inductance on the current path. a 0.1uf ceramic capacitor from vin to gnd, physically located near the device is strongly recommended to control the supply input transient. minimizing the parasitic inductance along the current path also alleviate the voltage transient at the supply input. output voltage filtering bypassing the output voltage with a 0.1uf ceramic capacitor improves the immunity of the device against output short circuit and hot plug/unplug of load. a lower esr capacitor results in lower voltage drop against a step load change. a large electrolytic capacitor from vout to gnd is also recommended. this capacitor reduces power supply transient that may cause ringing on the input. usb supports dynamic attachment (hot plug-in) of peripherals. a current surge is caused by the input capacitance of downstream device. ferrite beads are recommended in series with all power and ground connector pins. ferrite beads reduce emi and limit the inrush current during hot-attachment by filtering high-frequency signals. the dc resistance of the ferrite bead should be specially taken care to reduce the voltage drop. voltage drop and power dissipation temperature effect should be well considered when dealing with voltage drop and power dissipation. the maximum r ds(on) of the power switch is 100m ? under 25 o c junction temperature. if the device is expected to operate at 125 o c junction temperature, the rds(on) will become 100m ? * (1 + (125 o c - 25 o c) * 0.5%/ o c) = 150m ? where 0.5%/ o c is the approximated temperature coefficient of the r ds(on). if the maximum load current is expected to be 1.2a, the maximum voltage will become 1.2a * 150m ? = 180mv this in turn will cause power dissipation as 1.2a * 180mv = 215mw the temperature raise is calculated as 215mw * 160 o c/w = 35 o c the junction temperature is calculated as t a + 35 o c, where t a is the expected maximum ambient temperature. a few iterations are required until get final solutions. layout consideration the power circuitry of usb printed circuit boards requires a customized layout to maximize thermal dissipation and to minimized voltage drop and emi ? place the device physically as close to the usb port as possible. keep all traces wide, short and direct to minimized the parasitic inductance. this optimizes the switch response time to output short circuit conditions. ? place both input and output bypass capacitors near to the device. ? if ferrite beads are used, use wires with minimum resistance and large solder pads to minimize connection resistance. ? all vout pins should be connected together on the pcb. all vin pins should be connected together on the pcb. a pplication information + v bus gnd bus v out gnd oc# en# v in 1 2 3 45 6 7 8 UP7534bs8 www.datasheet.co.kr datasheet pdf - http://www..net/
