USB Type-C PD 20mΩ Sink and 39mΩ Source
Combo 2-in-1 Protection Switches
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 back-
to-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.
