These single-channel current-limited power switches from Diodes are optimized for USBs and other hot-swap applications and meet design requirements for laptop computers, tablets, and Chromebooks™, especially those deploying the new Type-C USB port.

This family of power switches incorporates 0.4 A current limiting while operating from a 2.7 V to 5.5 V supply with a maximum continuous load current rating of 0.2 A. Other protection features, such as 0.4 ms controlled rise and fall times, support hot-swap connections between computing, communication, and consumer electronics equipment and peripherals. In addition, under-voltage lockout (UVLO) and reverse-current blocking protect the input power supply while thermal protection prevents damage to the IC under heavy-overload or short-circuit fault conditions.

In full compliance with USB 2.0 and available with both polarities of enabling input, the AP21410 (active-low) and AP21510 (active-high) switches also benefit from a 95 MΩ on-resistance and a very low 1 μA shutdown current that contribute to reduced power consumption and extended battery life. Both versions of this power switch are supplied in a compact 6-pin U-DFN2018 package.
