Hell team,

I just wanted to know what will be voltage on the Gate pin w.r.t ground when the Vbat is 24V ,Please refer the screenshot

Hi Darshan,

The controller can drive GATE to VIN+12V max.

It is important to note that the controller uses linear regulation scheme to drive the FET and GATE voltage depends on the current flowing from source to drain.
