FPF2195UCX

Power Distribution Switches, Load Drivers Overview

The FPF2195UCX is a full-function load switch featuring an integrated P-channel MOSFET with a maximum on-resistance of 55 mΩ. It operates within an input voltage range of 1.8 V to 5.5 V and supports an adjustable current limit from 0.1 A to 1.5 A. The device includes thermal shutdown protection, under-voltage lockout, and reverse current blocking capabilities. It offers controlled turn-on, auto-restart functionality, and fast fault blanking times of 30 ns for hard shorts and 5 µs for moderate overcurrents. Shutdown current is less than 2 µA.

Power Distribution Switches, Load Drivers Feature Summary

• Integrates a current-limited P-channel MOSFET for system protection against large current conditions.
• Provides thermal shutdown and under-voltage lockout to prevent damage during continuous over-current or low voltage states.
• Features reverse current blocking to prevent internal current flow when the output voltage exceeds the input voltage.
• Supports logic-level control inputs compatible with low-voltage signals for direct interfacing.

Power Distribution Switches, Load Drivers Applications

• Peripheral ports and accessories
• Portable medical equipment
