High-side power switches ideal for USB ports and other hot-swap applications

Diodes Incorporated has introduced the AP22815 and AP22615 3A single-channel high-side power switches for USB ports and other hot-swap applications. These devices are intended to give protection for any sensitive electronic equipment used in a hot-swap situation, such as USB peripherals or external storage devices. These highly integrated high-side switches offer extensive port protection with auto-recovery, as well as over-current, over-voltage, short-circuit, and over-temperature. Also, they feature controlled rise-time and under-voltage lock-out, as well as a discharge function for external storage capacitors. Based on an N-channel MOSFET and the company’s patented copper-pillar packaging technology to produce a particularly low on-resistance, the power switches provide a wide input voltage range of 3V to 5V and an adjustable limited load current of up to 4A (AP22615 only). With a low RDS(ON) of just 40mOhm and high ESD protection (2kV human body model, 200V machine model), the devices are integrated load switches that are ideal for a range of applications, including netbooks, notebooks, tablets, USB chargers, set-top boxes, and other consumer electronics.
