MAX1693H - USB Current-Limited Switches

This page provides the datasheet information for the MAX1693H, a member of the MAX1693 USB Current-Limited Switches family.

Description

The MAX1693/(MAX1693H)/MAX1694 are current-limited, 60mΩ switches with built-in fault blanking.

Their accurate preset current limit of 0.7A to 1.0A makes them ideally suited for USB applications.

Features

  • to ensure that the USB port is protected. Built-in thermal-overload protection limits power dissipation and junction temperatures. All devices have accurate internal current-limiting circuitry to protect the input supply against overload. They are available in space-saving 10-pin µMAX packages.

19-1518; Rev 2; 9/01 MAX1693/(MAX1693H)/MAX1694 USB Current-Limited Switches with Fault Blanking General Description The MAX1693/(MAX1693H)/MAX1694 are current-limited, 60mΩ switches with built-in fault blanking. Their accurate preset current limit of 0.7A to 1.0A makes them ideally suited for USB applications. Their low quiescent supply current (14µA) and shutdown current (1µA) conserve battery power in portable applications. The MAX1693/(MAX1693H)/MAX1694 operate with inputs from 2.7V to 5.5V, making them ideal for both 3V and 5V systems. A fault signal notifies the microprocessor that the internal current limit has been reached.
