The MAX1564ETE+ is a triple 1.2A USB switch in 16 pin TQFN package. Each channel meets all IEC specifications for USB ports. The device is capable of supplying up to 1.2A from each output. It has multiple protections including thermal shutdown to limit junction temperature in case of prolonged short or overload condition. Reverse current protection circuitry blocks current flow from output to input regardless of switch state. The IC has accurate, user programmable current limiting circuitry to protect input supply against overload. Each output of MAX1564 has short circuit protection that latches off switch when output is shorted for more than 20ms thereby saving system power. Auto restart then tests shorted output with 25mA current to determine when short is removed then automatically restarts output. A 20ms fault blanking allows momentary faults to be ignored such as those caused when hot swapping into capacitive load. This feature helps to avoid issuing false alarms to host system.
