General Description

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.
