Power switches provide complete USB port protection
Diodes Incorporated has introduced a family of 6 high-side power switches offering complete 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 0.5A, 1.0A and 1.5A, and both polarities of enable input.To i
The AP21x2A products 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 7ms 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 Recognized and IEC 60950-1 CB Scheme Certified to ensure public safety and product quality. Their ambient operating temperature range is -40 to 85oC.
