GreenFET3™ Single N-Channel Reverse Blocking Integrated Power Switch

A team of engineers is ready to answer your questions

A Reverse-blocking, 36-mΩ, 2.2-A pFET IPS 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 integrated power 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 VOUT > VIN + 32 mV condition opens the switch). When OFF, the pFET’s internal body diode is connected to the higher voltage of VIN/VOUT to prevent reverse-path leakage current. The SLG59M1748C is an ideal pFET integrated power switch in any application where two power sources are likely to be multiplexed to one output.
