Diodes Inc - Higher current power switches optimized for USB

Provided in both SO-8 and MSOP-8L-EP packages, the power switches are a very simple, cost effective form-fit for a wide range of consumer electronics, communications and computing products. High-side devices, the AP2101 and AP2111 offer designers the choice of active-low and active-high enable respectively.



Characterized by a fast transient response time of just 5µs, the devices prevent unnecessary system shutdown/restart and generally improve overall system robustness. In addition, the power switches' automatic output discharge function ensures a quick and well defined discharge of the output voltage capacitor.



Like all other devices in the AP21XX family, the new devices provide a complete protection solution for applications subject to heavy capacitive loads and the prospect of short circuits. The AP21XX devices offer reverse current blocking, over-current, over-temperature and short-circuit protection as well as controlled rise time and under-voltage lockout functionality.



To help reduce system rail power requirements and associated circuit costs, the AP2101 and AP2111, also have a very tight, 2.45A current limiting tolerance. A 7ms deglitch capability on the open drain flag output prevents false over-current reporting and requires no additional external components.
