Description

The AW3511XS integrates a 64mΩ (typ.) P-channel MOSFET, which can operate over a wide input range of 1V to 5.5V. The AW3511XS features output slew rate control, limiting inrush currents during turn-on to protect downstream devices. In addition, AW35111S/AW35113S has QOD function which can prevent the output from floating when the switch is disabled. A smart pull-down resistor is used to the EN pin during initial power-up and disconnects once the EN pin voltage reaches the VIH level, then the standby current is very low and power loss can be reduced. There is a Reverse Current Protection(RCP) function for AW35112S/AW35113S when VOUT is 33mV(typ.) greater than VIN, which can prevent the current to flowing through the P-FET or the body diode. The AW3511XSCSR is available in WLCSP 0.618mm×0.618mm-4B package.
