The PD16876 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 one Pch power MOSFET circuits, which has a low-on resistance (100 m TYP.), in its switching block. This product 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 one channel of power switch, control input pin, and flag output pin to simultaneously control one USB port with a single IC. |
