The PD16855A/B/C/D is a dual high-side switch from NEC for use on the power supply bus of the Universal-Serial-Bus (USB). It features two Pch power MOSFETs in the switch part, each with low on resistance (100 mΩ TYP.), as well as over current detection, thermal shutdown and under voltage lockout circuits. The over-current-detect result can be reported to the controller by flag-pin.
This document is a datasheet for the NEC uPD16855A/B/C/D integrated circuit. The device features two Pch power MOSFET circuits built-in to serve as a power switch for Universal Serial Bus (USB) application power supply buses. It includes protection functions such as over-current detection, thermal shutdown, and under-voltage lock-out (UVLO).
