Description
The MAX1823 is a dual, current-limited switch with autoreset specifically made for USB applications.
The autoreset feature latches the switch off if the output is shorted, saving system power.
The switch reactivates when the short circuit is removed.
Features
- to ensure that the USB port is protected. Built-in thermal-overload protection limits power dissipation and junction temperature. Accurate internal current-limiting circuitry protects the input supply against both overload and short-circuit conditions. Independent fault signals (FAULTA and FAULTB) notify the microprocessor (µP) when a thermal-overload, current-limit, undervoltagelockout (UVLO), or short-circuit fault occurs. A 20ms fault-blanking feature ignores momentary faults, such as those c.
