Diodes AP21x2A dual channel high-side power switches

Diodes has introduced a family of six high-side power switches offering port protection for a wide range of self-powered and bus-powered USB and other hot-swap applications.

Designed to tolerate heavy capacitive loads and short circuits, the AP21x2A dual channel devices are available with maximum load current ratings of 0.5, 1.0 and 1.5 A.

To improve system robustness, the switches deliver a fast transient response of 2 µs to prevent spurious shutdown or restart. They provide tight tolerance current limiting at ratings of 0.8, 1.4 or 2.0 A, over-temperature and short-circuit protection as well as controlled rise-time and under-voltage lockout functionality.

They integrate an automatic output discharge function to provide controlled discharge of disabled output capacitor voltage and offer improvement in on-resistance over existing dual channel devices.

A 7 ms deglitch time on the power switch’s fault report flag prevents any false over-current reporting and does not require the addition of any external components.

The package options with industry standard pin-outs are: SO8, MSOP-8, MSOP-8-EP and DFN3030E-8.

The devices are UL recognised and IEC 60950-1 CB scheme certified.
