General Description

AOZ1382DI-01 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 sink function features Ideal Diode True Reverse Current

Blocking (IDTRCB). It supports power ORing configurations

and can sink current from the Type-C port through a back-toback

MOSFET with only 20 mΩ ON resistance from VBUS to

VCHG pin. The VBUS operating range is from 3.4 V to 23 V

under sink mode with absolute maximum rating of 28V on

both VBUS and VCHG pins. There is Under-Voltage Lock

Out (UVLO) and Over-Voltage Lock Out (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.

The source function provides power to the VBUS from V5V

through a separate back-to-back MOSFET with 39 mΩ ON

resistance. The input operating range at V5V pin is from 3.4 V

to 5.5 V. 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 500 mA to 3.5 A with

an external resistor. The source function 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

AOZ1382DI-01 has True Reverse Current Blocking (TRCB)

function in the source modes and Ideal Diode True Reverse

Current Blocking (IDTRCB) in the sink mode. The back-toback

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. AOZ1382DI is available

in a 3mm x 5.2mm DFN-20L package and can operate from

-40 °C to +85 °C temperature range.
