MAX1558, Dual 3mm x 3mm 1.2A/Programmable-Current USB Switches

The MAX1558/MAX1558H are dual, current-limited switches with autoreset for USB applications.

Autoreset latches the switch off if it is shorted for more than 20ms, saving system power.

The shorted output is then tested to determine when the short is removed to automatically restart the channel.

MAX1558 Features

* ensure that the USB port is protected. Built-in thermal-overload protection limits power dissipation and junction temperature. Accurate, programmable current-limiting circuitry protects the input supply against both overload and short-circuit conditions. 20ms fault blanking enables the circuit to ig
