Maxim Integrated
General Description
The MAX1693/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/MAX1694 operate with inputs from +2.7V to +5.5V, making them ideal for both +3V and +5V systems.
