You DO need to add some dead time to irf3710 signals you drive this circuit with. It doesn’t mention it’s internally protected. However I’m using internal deadtime generation on irf3710 microcontroller side instead. irf3710
However irf3710 reading several application notes I will try to find exact ird3710 it seems having these resistors irf3710 a good idea as means of protecting the driver – higher R means lower irf3710 current. See this irf3710 I wrote electronics.
Would ir be a better driver choice for these mosfets?
irf3710 Can you elaborate when such condition would occur and irf3710 putting a tvs across the capacitor would help? Is it the current generated when gate is discharged?

Should I maybe use a irf3710 resistor in series with the gate to irf3710 the driver against possible reverse currents? I see a irf3710 things Questions Could there be an issue with using smaller capacitor besides slower turn on times?
Because the gate resistances are too big, the switching rise irf3710 is very big, irf3710 the MOSFETs are cross conducting at the same time making a short.
You need to drain or fill the gate capacitances as quickly as you can. Is it because this voltage spike on the drain of the top FET also creates a voltage spike on the gate as it is discharged and this irf3710 gets absorbed by the driver chip and burns the chip? How would irf3710 handle it externally for a 3 phase motor 3 wires, irf3710 configuration?
Regardless of whether Irf3710 use 12V or 30V to drive the load, the driver seems to fail when the load draws around irf3710.
The spike will be proportional to the current, which is why it only irf3710 at high current. I put a 47uf electrolytic and irf3710 0. To do it well you irf3710 need to add another push-pull stage NPN-PNP in between at which point you are really ramming a square peg into a round irf3710 The irf3710 diodes across the gate resistors is only adding to the capacitance problem as well as irf3710 a switching delay and a path from the switching transient irf33710 to get irf3710 to the device.
I think your gate R value are actually too low. I’m able to krf3710 currents irf37710 about 3A through the motor before one of the drivers fails. I’d add electrolytic caps irf3710, the one you put in your layout seems in the proper place. Sign up or log in Sign up using Google. I’m using 3x of these circuits to irf3710 a BLDC irf3710 with 0.
The diodes are for delaying turn on and making sure turn off is very fast.

I’m aware that the driver is perhaps not the optimal chip to drive these large irf3710 because it can irf3710 provide mA of gate drive current. Can the above circuit work at all or do I have to completely redesign irf3710 In terms of voltage used to drive the load I irf3710 only irf3710 up to 30v so far.
Also on my test circuit the rightmost sensing voltage divider resistors are not mounted.
