MAX1922 - 1A Current-Limited Switch

MAX1922 Description

19-2254; Rev 3; 4/09 1A Current-Limited Switch for 2 USB Ports General .
The MAX1922 current-limited 70mΩ switch with built-in fault blanking provides an accurate, preset 1.

MAX1922 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 an

MAX1922 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. An overcurrent signal (OC) notifies the microprocessor that the internal current limit h
