General Description

The MAX1922 current-limited 70mΩ switch with built-in fault blanking provides an accurate, preset 1.4A to 2.1A current limit, making it ideal for dual USB applications.

Its low quiescent supply current (16µA) and standby current (1µA) conserve battery power in portable applications.

The MAX1922 operates with inputs from 2.7V to 5.5V, making it ideal for both 3V and 5V systems.

Overview

19-2254; Rev 3; 4/09 1A Current-Limited Switch for 2 USB Ports General.

Key Features

to ensure that the USB port is protected. Built-in thermal-overload protection limits power dissipation and junction temperature. The device also has accurate internal currentlimiting circuitry to protect the input supply against overload. The MAX1922 is offered in a space-saving 8-pin SO package and a 10-pin TDFN package and operates over the extended (-40°C to +85°C) temperature range. PART MAX1922ESA+ MAX1922ETB+ Features o Accurate Current Limit (1.4A min, 2.1A max) o 10ms Internal OC Blank.
