5.5V, 23mΩ, 4A Load Switch with Discharge and Reverse Current Blocking

The SLG59M1649V is a self-powered, high-performance, 23mΩ pFET load switch designed for 1.5V to 5.5V power rail applications up to 4A. When enabled, internal reverse-current protection will quickly open the switch in the event a reverse-voltage condition is detected (a VOUT + 50 mV > VIN condition opens the switch). Upon the detection of a reverse condition, an open-drain FAULT output is asserted. In the event the VIN voltage is too low, the load switch also contains an internal undervoltage lockout (UVLO) threshold monitor to keep or turn the switch OFF. Designed to operate over a -40 °C to 85 °C range, the SLG59M1649V is available in a RoHS-compliant, ultra-small 1.0mm x 1.6mm STDFN package.
