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. |
