Description

The PD16875 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 two Pch power MOSFET circuits, each of which has a low-on resistance (100 m TYP.), in its switching block. This product is a low-current-consumption version of the PD16855B that boasts an operating current consumption of as low as 100 A (MAX.).

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 two channels of power switches, control input pins, and flag output pins to simultaneously control two USB ports with a single IC.
