Design a Custom BoardAbout This Component
High-side power switch IC for USB and hot-swap applications with 1.5A current limiting and integrated protection. Features 95mΩ on-resistance, over-current/thermal limiting, reverse current blocking, and open-drain flag output with 7ms deglitch. Operates from 2.7V–5.5V with active-high enable (AP2191 variant) and <1µA shutdown current.
Package: SC-74A-5 · 5 pins
Why does this need a breakout?
Tiny 0.95mm pitch SMD makes hand-soldering risky and breadboarding impossible. A breakout board brings these single-gate logic ICs and analog switches to standard 0.1" headers, enabling rapid prototyping and reliable connections without microscopy skills or rework tools.
