When TLP250 drives NMOS, I would like to ask you how to choose between D1 and D2. I simulated it for a while. Yes, I would like to ask you how this control MOS is turned off. Thank you.

Does MOS tube have no body diode?

I did not draw the diode in the body.

Does D1 and D2 play a role in quickly discharging charges? ? ? Or is it anti-static to protect the MOS tube? ? ?

My analysis should be to protect the MOS tube.
Maureen postato su January 12, 2021
D1 and D2 limit the GS voltage of the MOS tube to prevent the GS voltage from being too high to break down the GS, thereby protecting the MOS tube; how to turn off the MOS tube depends on the internal logic of the TL250, as long as the GS voltage is less than the MOS tube turn-on voltage, it can be turned off. Off.
