Description
The MAX1940 triple current-limited switch with autoreset supplies a guaranteed 500mA load per channel in accordance with USB specifications.
Features
- 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. Independent open-drain fault signals ( FAULTA , FAULTB , and FAULTC ) notify the microprocessor when a thermal-overload, current-limit, undervoltage lockout (UVLO), or short-circuit fault occurs. A 20ms fault-blanking feature enables the circuit to ignor.
