Summary

The USB interface is no longer used just for PCs and their peripheral devices, but for all types of electronic equipment requiring high speed transmission of large amounts of data. As equipment becomes faster and content more multimedia driven measures must be taken to minimize power consumption.
ROHM's power switch ICs utilize the most advanced circuitry for low power operation and incorporate multiple protection functions, including thermal shutdown, overcurrent protection, and undervoltage malfunction prevention, to ensure the utmost in reliability.

High Side Switch ICs

Features

ROHM's power management switch ICs integrate a low ON-resistance MOSFET and multiple protection functions on a single chip.

· USB port power supply control built in
· Built-in soft start function mitigates inrush current
· Reverse current prevention function ensures complete output OFF
· Equipped with thermal shutdown circuit
· Low ON-resistance switch
· Current consumption: 90µA (ON), 0µA (OFF)
