AP2401/AP2411
2.0A SINGLE CHANNEL CURRENT-LIMITED
POWER SWITCH WITH LATCH-OFF
Description Pin Assignments
The AP2401 and AP2411 are single channel current-limited
(Top View)
integrated high-side power switches optimized for Universal Serial
Bus (USB) and other hot-swap applications. The family of devices GND 1 8 NC
complies with USB standards and is available with both polarities of

The devices have fast short-circuit response time for improved overall
system robustness, and have integrated output discharge function to EN 4 5 FLG
