General Description

The A4772 is a low voltage, single N-MOSFET high-side power switch, optimized for self-powered and bus-powered Universal Serial Bus (USB) applications.

The A4772 equipped with a charge pump circuitry to drive the internal MOSFET switch;

the switch's low RDS(ON), 80mΩ, meets USB voltage drop requirements and a flag output is available to indicate fault conditions to the local USB controller.

Overview

AiT Semiconductor Inc.

www.ait-ic.com A4772 POWER SWITCHES WITH FLAG 80mΩ, 0.5A/0.8A/1A/1.

Key Features

include soft-start to limit inrush current during plug-in, thermal shutdown to prevent catastrophic switch failure from high-current loads, under-voltage lockout (UVLO) to ensure that the device remains off unless there is a valid input voltage present. The maximum current is limited to typically 2.1A/1.5A/1A/0.65A through the switch of A4772A/B/C/D, lower quiescent current as 25uA making this device ideal for portable battery-operated equipment. The A4772 is available in SOT-25 package.
