FPF2260ATMX中文资料Over-Voltage/Under-Voltage Protection controller with negative voltage protection数据手册ONSEMI规格书

描述 Description

FPF2260ATMX is an OVP and UVLO controller with reverse / negative voltage protection. The device controls and drives a pair of external N−MOSFET that can operate over an input voltage range of 2.8 V to 23 V. In that way, with OVP feature implemented, the system can allow huge current as long as the external MOSFET can handle.
When the input voltage exceeds the over−voltage threshold or lower than under−voltage threshold, the external FET is turned off immediately to prevent damage to the protected downstream components.
When the input voltage is stressed a negative voltage, the external FET will also be turned off and prevent OUT dropping to negative voltage.
FPF2260ATMX is available in a small X2QFN12 package and operate over the free−air temperature range of −40°C to +85°C.
