The MAX1946 single current-limited switch with autoreset supplies a guaranteed 500mA load in accordance with USB specifications.

The MAX1946 operates from a 2.7V to 5.5V input supply and consumes only 40µA of quiescent current when operating and only 3µA in shutdown.

Selectable active-high/active-low control logic and shutdown control provide additional flexibility.

to protect the USB port. Built-in thermal-overload protection turns off the switch when the die temperature exceeds +160°C. Accurate internal current-limiting circuitry protects the input supply against both overload and shortcircuit conditions. An open-drain fault signal, (FAULT), notifies the microprocessor (µP) when a thermal overload, current-limit, undervoltage lockout (UVLO), or short-circuit fault occurs. A 20ms fault-blanking feature enables the circuit to ignore momentary faults, such a.
