AOZ1381DI - Type-C PD Sink Combo 2-in-1 Protection Switches

Datasheet Summary

Description

AOZ1381DI integrates two back-to-back power switches and control circuitry into one single package to provide all the functionality and protection needed for sourcing and sinking current through a USB Type-C port with PD capability.

Features

a FON pin for fast turn-on capability to support the Fast Role Swap (FRS) function. AOZ1381DI has True Reverse Current Blocking (TRCB) function in both sink and source modes. The back-to- back MOSFET automatically prevents reverse current when the output voltage exceeds the input voltage. The device is also protected by thermal shutdown. There are two FLTB flags, FLTB_SNK for sink mode and FLTB_SRC for source mode, which are open drain outputs and each will be pulled low independently for fault.

ALPHA & OMEGA AOZ1381DI SEMICONDUCTOR USB Type-C PD 32mΩ Sink and 39mΩ Source Combo 2-in-1 Protection Switches General Description AOZ1381DI integrates two back-to-back power switches and control circuitry into one single package to provide all the functionality and protection needed for sourcing and sinking current through a USB Type-C port with PD capability. The device can sink current from the Type-C port through a backto-back MOSFET with only 32mΩ ON resistance from VBUS to VCHG pin. The VBUS operating range is from 3.4V to 22V under sink mode with absolute maximum rating of 28V on both VBUS and VCHG pins. There is under-voltage lockout (UVLO) and over-voltage lockout (OVLO) on VBUS.
