G3712B61U 电子元器件 GMT（致新） 封装WLCSP4X4-16 批次22+

General Description
The G3712 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.
G3712 is available in the WLCSP4X4-16 package.
