AOZ15333DI Datasheet | Alpha & Omega Semiconductors

Description The AOZ15333DI is a current-limited load switch targeting applications that require prehensive protections. The input operating voltage range is between 3.3 V and 5.5 V. The output terminal is rated 39 V absolute maximum. The internal current limiting circuit protects the supply from large load current. The current limit level is set with an external resistor. The soft-start circuit controls inrush current due to highly capacitive loads. The device features very low quiescent current of 125 µA. The supply current reduces to less than 6 µA in shutdown. It has under-voltage lockout, over-voltage protection (OVP) and over temperature protections. The AOZ15333DI has True Reverse-Current Blocking (TRCB) protection to avoid undesired reverse-current from VOUT to VIN. The AOZ15333DI supports USB PD Fast Role Swap (FRS). When FON pin is high, the device is in fast turn-on mode to ensure output voltage rises quickly to meet USB PD spec. The device also features fast recovery to turn on the power switch once reverse current blocking protection is de-activated. The AOZ15333DI is available in 3 mm x 3 mm DFN-12L package.
