When a positive pulse is applied, it passes directly through the diode D_ON and charges the Gate of the mosfet. When the output stage of the main driver is closed, then through the pull-up resistor PULL_DOWN opens Q_OFF and instantly discharges the Gate charge through itself, which leads to the instantclosure of the mosfet!

Also if we use toff transistor the toff path did not return the gate driver so negative bias voltage meaningles here i suggest to not use it. Now design has two seperate gate resistor for on and off we can arrenged resistor for fast discharge the gate

Hi!
in the picture above, there is just one of the best solutions for managing powerful mosfets. I always use this and it works great

But I don't know the whole scheme that you use, it can also be good. I would prefer a circuit with a locking transistor, for example Q_off IRFL9110TRPBF, pull_down 4.7K, D_on any schottky per 1 ampere

Hi

The design is done i shared the pdf files if there is no further update i will upload to github

The only clarification is that all layers should be made as thick as possible, at least 75 microns, but it is better if 100 microns

Hello

I placed 4 pin header close to the microcontroller also can be programmed via esp8266

Ok i will make layer stack table for manufacturing

also high power path not painted can be supported vıa solder ıt will be reduced the board price
