General 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 500mA 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.
