Product Summary
The MAX1562HESA+ is a programmable 4A USB current-limited switch with autoreset and fault blanking. The MAX1562HESA+ single current limited switches provide up to 4A to power up to eight USB ports. It operates from a 4V to 5.5V input supply and consume only 40μA of quiescent current when operating and only 3μA in shutdown. The MAX1562HESA+’s autoreset features latches the switch off if the output is shorted, thereby saving system power. When the short is removed, the switch is reactivated. A fault-blanking feature enables the circuit to ignore momentary faults, such as those caused when hot swapping a capacitive load, preventing false alarms to the host system. Fault blanking also prevents fault signals from being issued when the device powers up the load. The applications of the MAX1562HESA+ include notebook computers, desktop computers, USB ports and Hubs, PDAs and palmtop computers, docking stations.
