AP2401 / AP2411 Power Switches

A 2.0 A single channel current-limited power switch with latch-off from Diodes

Image of Diodes Incorporated's AP2401/AP2411 Power Switches Diodes Incorporated introduces the AP2401 and AP2411 single-channel power switches designed to help raise USB port protection levels. These 2 A rated high-side power switches ensure fast and accurate latching-off of output current in the event of over-current detection. They also offer a choice of active-low and active-high enable operation, optimized for self-powered and bus-powered USB 2.0 and 3.0. Other 3 V to 5 V hot-swap consumer electronics, as well as computing, and communication applications, such as notebook computers and set-top boxes. To increase overall system robustness, the power switches’ fast short-circuit response time of 2μs means unnecessary system shutdown or restart can be avoided, while their integrated output-discharge function provides full and controlled discharge of output capacitor voltage when disabled. To minimize voltage drop losses in higher current systems, the AP24xx devices exhibit an on-resistance of only 70 mΩ under 2 A continuous operation. Providing a complete protection solution for any equipment subject to short circuits and heavy capacitive loads, the power switches incorporate over-current, short-circuit, over-temperature under-voltage lockout and reverse current-blocking protection. The power switches’ tight current-limiting tolerance also reduces power-rail current requirements, and therefore overall system cost. The AP2401 and AP2411 power switches are provided in space-saving DFN3030E-8 and industry-standard SO-8 and MSOP-8-EP packages.
