Product Details

The MAX8586 single current-limited switch controls up to 1.2A to power USB applications and has multiple protection features including thermal shutdown, internal current limiting, and reverse current protection. The thermal shutdown limits junction temperature during a prolonged short or overload condition. The internal current-limiting circuitry protects the input supply against overload and is programmable using an external resistor. The MAX8586 meets all IEC specifications for USB ports.

The IC latches off when the output experiences a short circuit for more than 20ms, saving system power. Auto-restart tests the shorted output with a 25mA current to determine if the short still exists. Once the short is removed, the MAX8586 automatically restarts the output. An open-drain fault signal notifies the system that the internal current limit has been reached. A 20ms fault-blanking feature allows the circuit to ignore momentary faults such as those caused when hot-swapping into a capacitive load. An ENRESET input is available to disable the auto-restart function.

The MAX8586 features a SEL input that programs ON to be either active high or active low. The IC is supplied in a space-saving, 8-pin, 3mm x 3mm TDFN package.
