The MAX1564 triple, current-limited USB switch comes

in a space-saving, 16-pin, 4mm x 4mm thin QFN pack-

age. 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 protec-

tion that latches off the switch when the output is short-

ed 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 open-

drain fault signals notify the microprocessor that the

internal current limit has been reached. A 20ms fault-

blanking 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.
