PD16874
QUAD Pch HIGH-SIDE SWITCH FOR USB
DESCRIPTION
The
碌
PD16874 is a power switch IC with an overcurrent limiter that is used for the power bus of a Universal Serial
Bus (USB). This product has Pch power MOSFET circuits, each of which has a low-on resistance (100 m鈩?TYP.), in
its switching block.
In addition, the IC is also equipped with an overcurrent detector that is essential for a host/hub controller
conforming to the USB Standard, so that the IC can report an overcurrent to the controller. Moreover, a thermal
shutdown circuit and an undervoltage lockout circuit are also provided as the protection circuits of the IC.
This product has four channels of power switches, control input pins, and flag output pins to simultaneously
control four USB ports with a single IC.
