The MAX1562/MAX1562H/MAX1563 single currentlimited
switches provide up to 4A to power up to eight
USB ports. They operate from a 4V to 5.5V input
supply and consume only 40μA of quiescent current
when operating and only 3μA in shutdown.
The MAX1562/MAX1562H/MAX1563s’ autoreset feature
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.
