AOZ15953DI Datasheet | Alpha & Omega Semiconductors

Description The AOZ15953DI is a protection switch intended for USB Type-C PD EPR applications that require reverse current protection. The input operating voltage range is between 2.7 V and 5.5 V, and the VOUT terminals are rated at 60 V Absolute Maximum. AOZ15953DI provides under-voltage lockout, over-voltage, and over-temperature protection. The FLTB pin flags thermal shutdown and over-voltage faults. AOZ15953DI 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 the USB PD specification. AOZ15953DI features Ideal Diode True Reverse Current Blocking (IDTRCB) protection to prevent reverse current flow from VOUT to VIN at any load. This feature plies with the USB PD specification. The device also features fast recovery from reverse blocking to prevent excessive VOUT droop in power swap applications The AOZ15953DI is available in a thermally enhanced 4mm x 4mm DFN-16L package which can operate over -40 °C to +125 °C junction temperature range.
