Description

The AW3511X family load switch integrates a 64mΩ (typ.) P-channel MOSFET, which can operate over a wide input range of 1V to 5.5V. The AW3511X features output slew rate control, limiting inrush currents during turn-on to protect downstream devices. In addition, AW35111/ AW35113/AW35114 have QOD function which can prevent the output from floating when the switch is disabled. A smart pull-down/up 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 AW35112/AW35112B/AW35113 when VOUT is 33mV(typ.) greater than VIN, which can prevent the current to flowing through the P-FET or the body diode. There is no output discharge resistor for AW35112 and AW35112B. The AW35111FDR/112FDR/113FDR/114FDR is available in FCDFN 0.8mm×0.8mm-4L package, and the AW35111FOR/112BFOR is available in FOWLP 0.8mm×0.8mm-4B package, and the AW35113FOR is available in FOWLP 0.9mm×0.9mm-4B package.
