onsemi FPF2286UCX

FPF2286 is an OVP with integrated low on−resistance single channel switch. The device contains an N−MOSFET that can operate over an input voltage range of 2.8 V to 23 V and can support a maximum continuous current of 4 A. When the input voltage exceeds the over−voltage threshold, the internal FET is turned off immediately to prevent damage to the protected downstream components. FPF2286 is available in a small 6−bump WLCSP package and operate over the free−air temperature range of -40°C to +85°C. FPF2286 is an OVP power switch to protect next stage system which is optimized to lower voltage working condition. The device includes ultra low on−resistance power FET (25 mΩ) and super fast OVP response time (40 ns). The FPF2286 integrates an N−type MOSFET with 25 mΩ resistance. The power FET can work under 2.8 V ~ 23 V and up to 4 A DC current capability. The FPF2286 is supplied by IN. IN will be firstly supplied by OUT when the device is working under USB On−The−Go (OTG) condition. There is no specified enable pin for FPF2286. However, the OVLO can be used as an active LOW enable pin to be controlled by a GPIO. When OVLO pin is connected to a high level (higher than 1.2 V), the internal FET will be turned off. When OVLO pin is connected to 0 V, the FET will be turned on as long as VIN is not higher than 6.8 V. FPF2286 power switch will be turned off when the voltage on IN is lower than the UVLO threshold VIN_UV_F. Whenever VIN voltage ramps up to higher than VIN_UV_R, the power FET will be turned on automatically after tDEB de−bounce time if there is no OV or OT condition. The power FET will be turned off whenever VIN voltage higher than VIN_OVLO. The value of VIN_OVLO can be set
