UPD16855A Description
This product is the power switch IC with over current limit, used for the power supply bus of the Universal-SerialBus (USB). 2 circuit builds in the Pch power MOSFET in the switch part, and this product realizes low on resistance (100 mΩ TYP.) respectively. And the over current detection, the thermal-shutdown circuit, an under voltage locked-out (UVLO) circuit whose functions are necessary in the Host/HUB-controller...
UPD16855A Key Features
- Over-current detection circuit is built in and its result is outputted from flag-pin (“L” active)
- Prevent from dropping power supply by over current limit circuit
- Switch on/off control is possible by the control-pin
- 8 pin DIP/SOP package
