GreenFET Dual P-Channel Reverse Blocking Load Switch

The SLG59M1640V 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 power switch also contains an internal UVLO threshold monitor to keep or to turn the switch OFF. For fast load turnoff when either switch is disabled (ONx = LOW‑to‑HIGH), each channel has its own fast discharge transistor that connects an internal 150 Ω RDSON transistor to the ground. 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 SLG59M1640V is available in a RoHS‑compliant, ultra-small 1.6 mm x 1.0 mm STDFN package.
