DUAL HIGH-SIDE SWITCH FOR USB APPLICATION
DESCRIPTION
This product is the power switch IC with over current limit, used for the power supply bus of the Universal-Serial-
Bus (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 of the USB standard are built in.
And the over-current-detect result can be reported to the controller by flag-pin.
This product builds in each two circuits of the power switch, control-pins and flag-pins, and this IC can be able to
control the power supply bus in 2 USB port.
There are four kinds of this product by the input logic of the control signal and switch operation in over-current
detect.
FEATURES
• Pch power MOSFET, 2 circuit building in
• 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
• Thermal shutdown circuit building in
• Under Voltage Locked Out (UVLO) circuit building in
• Switch on/off control is possible by the control-pin.
• 8 pin DIP/SOP package
