GreenFET3™ Dual P-Channel Reverse Blocking Integrated Power Switch

A team of engineers is ready to answer your questions

A 1.6 mm², Dual-channel 45 mΩ/2 A Power Switch with Reverse-Current Blocking, VOUT discharge, and Active LOW ON-OFF Control

The SLG59M1640V is a dual-channel, 45 mΩ PMOS power switch designed to switch 1.5 to 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 ground. Each power 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 x 1.0 mm STDFN package.
