Description
The SLG59M1639V is a dual‑channel, 45mΩ PMOS load switch designed to switch 1.5V to 5.5V power rails up to 2A in each channel. When either channel is enabled, reverse‑current protection will quickly open the switch in the event a reverse‑voltage condition is detected (a VOUT > VIN + 50mV condition opens the switch). If 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 temperature range, the SLG59M1639V is available in a RoHS‑compliant, ultra‑small 1.6mm x 1.0mm STDFN package.
