Overview
Description
Operating from a 1.6V to 5V power supply, the SLG59M1748C is a self‑powered, high‑performance, 36mΩ pFET load switch designed for high‑side power‑rail applications up to 2.2A. When ON, internal reverse‑current protection will quickly open the switch in the event of a reverse‑voltage condition is detected (a VOUT > VIN + 32mV 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 load switch in any application where two power sources are likely to be multiplexed to one output.

GFET as alternative
Hi guys ! In our original design, we're using RT9742SNGV on 3V3(0.5A) net but unfortunately, Richtek has shortage issues. Is GFET's has some alternatives? Small package, low pin count, reverse voltage detection are the critical.
