Overview
The FPF2702MX, part of the AccuPower™ FPF270X series from onsemi, is a high-performance current-limit load switch designed to provide comprehensive protection to systems and loads from excess current conditions. This device features a wide input voltage range of 2.8 V to 36 V and an adjustable current limit from 0.4 A to 2.0 A. The FPF2702MX incorporates a slew-rate-controlled N-channel MOSFET to prevent power bus disturbances caused by hot plugging or momentary excess load demands. It is available in a space-saving, lead and halogen-free, 8-lead SO8 package.
