The SLG59M1639V is a dual‑channel, 45 mΩ PMOS load switch designed to switch 1.5 to 5.5 V power rails up to 2 A in each channel. When either channel is enabled, reverse‑current protection will quickly open the switch in the event of a reverse‑voltage condition is detected (a VOUT > VIN + 50 mV condition opens the switch). In the event that the channel’s VIN voltage is too low, the load switch also contains an internal UVLO threshold monitor to keep or to turn the switch OFF. Each load switch is independently controlled via its own low‑voltage compatible CMOS input. Designed to operate over a -40 °C to 85 °C range, the SLG59M1639V is available in a RoHS‑compliant, ultra‑small 1.6 mm x 1.0 mm STDFN package.
