AOZ1380DI Datasheet | Alpha & Omega Semiconductors

Description AOZ1380DI 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 20mΩ 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. The sink switch has an active low enable input to support dead battery operation and its soft-start is adjustable through an external capacitor through the SS pin. AOZ1380DI also offers a current-sourcing path from 5V power supply to VBUS through a separate back-to-back MOSFET with 39mΩ ON resistance. The input operating range at V5V pin is from 3.4V to 5.5V. The sourcing switch is also protected by UVLO and OVLO. There is internal soft-start to control inrush current. The current limit can be adjusted from 500m A to 3.5A with an external resistor. The device has short circuit protection that shuts off the switch quickly to prevent input droop and system brown out. The sourcing switch also features a FON pin for fast turn-on capability to support the Fast Role Swap (FRS) function. AOZ1380DI 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 condition. AOZ1380DI is available in a 3mm x 5.2mm DFN-20L package and can operate from -40°C to +85°C temperature range.
