USB PD和Type-C电源开关

　　G3712BB61U 电子元器件 GMT（致新） 封装WLCSP4X4-16 批次22+

　　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.
