Description
The MAX1564 triple, current-limited USB switch comes in a space-saving, 16-pin, 4mm x 4mm thin QFN package. Each channel meets all IEC specifications for USB ports. The device is capable of supplying up to 1.2A from each output. The MAX1564 has multiple protection features, including thermal shutdown to limit junction temperature in case of a prolonged short or overload condition. Reverse-current protection circuitry blocks current flow from output to input regardless of the switch state. The IC has accurate, user-programmable current-limiting circuitry to protect the input supply against overload.

Each output of the MAX1564 has short-circuit protection that latches off the switch when the output is shorted for more than 20ms, thereby saving system power. Auto-restart then tests the shorted output with a 25mA current to determine when the short is removed, then automatically restarts the output. Independent opendrain fault signals notify the microprocessor that the internal current limit has been reached. A 20ms faultblanking feature allows momentary faults to be ignored, such as those caused when hot-swapping into a capacitive load. This feature helps avoid issuing false alarms to the host system. Blanking also suppresses errant fault signals when the device is powering up.
