Two power switches from Diodes are designed to latch-off output current in the event of over current detection in USB ports.

These 2A rated, high-side power switches can be used for either active low enable and active high enable operation and are optimised for self-powered and bus-powered USB 2.0 and 3.0 and other 3-5V hot-swap consumer electronics applications.

A short circuit response time of 2µs will mean that unnecessary system shutdown or restart can be avoided.

An integrated output discharge function provides full and controlled discharge of output capacitor voltage when disabled. 

To minimise voltage drop losses in higher current systems, the AP24xx devices exhibit an on-resistance of only 70mohm under 2A continuous operation.

The devices also have over-current, short-circuit, over-temperature under-voltage lockout and reverse current blocking protection.  

The AP2401 and AP2411 power switches are available in 8-leaded DFN3030E-8 and industry standard SO-8 and MSOP-8-EP packages.
