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.
