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.
