Hot-swap USB loads with 0.2A power switch

06-07-2015 | Diodes Inc | Power

Optimized for USB and other hot-swap applications, the AP21410/AP21510 single-channel current limited power switches introduced by Diodes Incorporated target manufacturers of laptop computers, tablets and Chromebooks, especially those deploying the new Type-C USB port. The family of power switches incorporates 0.4A current limiting, while operating from a 2.7V to 5.5V supply with a maximum continuous load current rating of 0.2A. Other protection features, such as 0.4ms 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 enable input, the AP21410 (active-low) and AP21510 (active-high) switches also benefit from a 95mohm on resistance and a very low 1µA shutdown current that contribute to reduced power consumption and extended battery life. Both versions are supplied in a compact 6-pin U-DFN2018 package, says the company.
