General Description
The G3712B is a precision adjustable current-
limited power switch for USB PD application.
The device is equiped with UVLO and OT protection.
VBUS pin can stand 29V ensures the device is
able to work on a USB PD port; ILIM pin defines the
over-current limit threshold; FLT pin indicates
when a fault condition has occurred.
The device has built in soft start to minimize current
surges during normal turn on. However, user can
disable the soft start and request a fast output by
pulling FO pin HIGH.
A fast RCP recovery circuit has been added to the
switch to prevent any reverse current flowing back
to power source at all times. When exiting from reverse
current protection state, the power MOSFET
will turn on within 50μs. The fast RCP recovery ensures
the voltage on VBUS doesn’t drop too much
in a power source swap application.
G3712B is available in the WLCSP4X4-16 package.
