MAX1607 - USB Current-Limited Switch

General Description

The MAX1607 is a current-limited 60mΩ switch with built-in fault blanking.

Its accurate, preset 0.7A to 1.0A current limit makes it ideal for USB applications.

Its low quiescent supply current (14µA) and standby current (1µA) conserve battery power in portable applications.

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 MAX1607 is a pin-compatible upgrade to Texas Instruments’ TPS2014, TPS2015, and TPS2041 for USB.

19-1544; Rev 0; 10/99 USB Current-Limited Switch in Pin-Compatible Package General Description The MAX1607 is a current-limited 60mΩ switch with built-in fault blanking. Its accurate, preset 0.7A to 1.0A current limit makes it ideal for USB applications. Its low quiescent supply current (14µA) and standby current (1µA) conserve battery power in portable applications. The MAX1607 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 has been reached. A 10ms overcurrent-blanking feature allows momentary faults (such as those caused when hot-swapping into a capacitive load) to be ignored, thus preventing false alarms to the host system.
