Controller with Negative
Stress Protection

FPF2260ATMX

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.
