Overview

The AP22814AW5-7 is a single-channel, P-channel load switch designed for high-side power distribution. It provides up to 3.0A of continuous output current with integrated protection features including fixed current limiting, over-temperature protection, and a fault report flag.

Why Choose This Part

The device features a low Rds(on) of 50mOhm to minimize power dissipation and voltage drop across the switch. It includes built-in soft-start with a 0.6ms rise time to prevent supply spikes and a 6ms blanking time on the fault flag to eliminate nuisance tripping from capacitive loads.

Applications

USB Port Protection
Protects host controllers and hubs from over-current and short-circuit conditions in USB 2.0 and 3.0 applications.
Hot-Swap Power Distribution
Manages inrush current for peripheral devices and plug-in modules to prevent system voltage droops.
Battery-Powered Handhelds
Efficiently switches power rails in mobile devices while maintaining a low shutdown current of 0.1uA.
Set-Top Box Power Management
Provides reliable rail switching and protection for external storage or connectivity interfaces.

Getting Started

When designing with the AP22814, place a 0.1uF or larger ceramic capacitor close to the input pin and ensure the FLG pin is pulled up to the logic supply via a 10k to 100k ohm resistor. Engineers should verify the enable logic (Active High for this variant) against their controller's GPIO state during power-up to prevent unintended turn-on.
