The MAX1693HEUB+T is a current-limited power switch with built-in fault blanking, ideal for USB applications. It offers an accurate preset current limit ranging from 0.7A to 1.0A, with guaranteed 0.75A short-circuit protection.
This device operates with input voltages from 2.7V to 5.5V, making it suitable for both 3V and 5V systems. It features a 10ms fault-blanking timeout to ignore momentary faults during hot-swapping or power-up, preventing false alarms. The switch has a low quiescent supply current of 14µA and a shutdown current of 1µA, conserving battery power in portable devices.
Key features include thermal shutdown protection and a status flag to notify microprocessors of overcurrent conditions. The MAX1693HEUB+T is available in a space-saving 10-pin uMAX package, suitable for surface mount applications.
Applications include USB ports and hubs, notebook computers, portable equipment, docking stations, and hot-plug-in power supplies.
