SLG59M1748C

A Reverse-blocking, 36-mΩ, 2.2-A pFET load switch in a 0.64 mm² WLCSP

Operating from a 1.6 V to 5 V power supply, the SLG59M1748C is a self-powered, high-performance, 36 mΩ pFET load switch designed for high-side power-rail applications up to 2.2 A. When ON, internal reverse-current protection will quickly open the switch in the event of a reverse-voltage condition is detected (a V_OUT> V_IN+ 32 mV condition opens the switch). When OFF, the pFET’s internal body diode is connected to the higher voltage of V_IN/V_OUTto prevent reverse-path leakage current. The SLG59M1748C is an ideal pFET load switch in any application where two power sources are likely to be multiplexed to one output.
