US222 Datasheet PDF - UTC 0.5A TO 2.0A HIGH-SIDE POWER DISTRIBUTION SWITCHES Specs

US222 - 0.5A TO 2.0A HIGH-SIDE POWER DISTRIBUTION SWITCHES

Datasheet Summary

Description

The UTC US222 are low voltage cost-effective high-side power switches with flag function.

These devices are particularly suitable for self-powered and bus-powered USB applications.

The build-in N-MOSFET’s RDS(ON) which meets the requirements of USB voltage drop is as low as 85 mΩ.

UNISONIC TECHNOLOGIES CO., LTD US222 Preliminary LINEAR INTEGRATED CIRCUIT 0.5A TO 2.0A HIGH-SIDE POWER DISTRIBUTION SWITCHES  DESCRIPTION The UTC US222 are low voltage cost-effective high-side power switches with flag function. These devices are particularly suitable for self-powered and bus-powered USB applications. The build-in N-MOSFET’s RDS(ON) which meets the requirements of USB voltage drop is as low as 85 mΩ. The UTC US222 contains a charge pump circuitry to drive the internal MOSFET switch and also incorporate such protection circuits: soft-start circuit protect these devices from being damaged by limiting inrush current during plug-in; thermal shutdown circuit is used to prevent catastrophic switch failure from high-current loads.
