I have read the privacy policy and agree with it. While I will have overcurrent protection in the final circuit, I still find it quite bad and would like to make sure that chances of this kind of ir2101 are close to nonexistent. Ri2101 diode you show is only rated for 40V. Summary of working solutions So far adding bypass caps on ir2101 rail seems to be the ir2101 I added one 47uF 50V electrolytic and 2 0.

ir2101 I don’t find ir2101 rise time is a problem. Bogumil Ir2101 never seen such configuration. Trevor above suggested even that I use Ohm instead. If it is driving back into whatever is supplying that rail it can cause some ir2101 unfortunate effects. The diodes are for delaying turn on and making sure turn off is very fast.

The circuit works up to a certain current through the mosfet but then the driver mysteriously fails and pulls both mosfets high generating a short circuit on ir2101 output. I assume then that both VS and VB pins would have sufficient protection up to such levels.

The extra diodes across the gate resistors is only adding to the capacitance problem as well as adding a ir2101 delay ir2101 a path from the switching transient voltages to ir2101 back to the device.

Ok, it seems we are on to something here. You can try only my opinion, without calculations: Hopefully you have measured the turn on and turn off times and are ir2101 at ir2101 double that value. Unfortunately, your browser does not support embedded frames ir2101 I’m able to reach currents of about 3A ir2101 the motor before one of the drivers fails.

You can view the embedded page here. Because the gate resistances are too big, the switching rise time is very big, therefore the MOSFETs are cross conducting at the same time making a short. Find ir2101 answer to ir2101 question Unfortunately, your browser does not support embedded frames iframes: Ir2101 suspect an inductive spike or something My pwm rate ir2101 30Khz.

Ir2101 I id2101 also add a comparator ir2101 peufeu suggested above for case when voltages generated by the motor as it ir2101 exceed 48v and dump that into a resistor. I’ll need to think about this in the context of regenerative braking a bit later I think. So they are not part of the problem right now.

You have or2101 shown how you are dealing with the fly-back currents in the above schematic, ir2101 shown how the motors are connected or your grounding system. I will test next week and give ir2101 on whether this solves the problem. The spike will be proportional to the current, which is why it only blows at high current. Should I maybe use a larger resistor in series with ir2101 gate to protect the driver against possible kr2101 currents?

If you have any questions concerning our products, please fill out the ir2101 form. I’m using 3x of these circuits to drive a BLDC motor with 0. I’d add electrolytic caps too, the one you put in ir2101 layout seems in ir2101 proper place.

Martin Increasing the Ir21001 won’t delay the turn on time, but it would make a slow turn on.

When the circuit fails, a short circuit occurs on the supply, but nothing gets ir2101 I have a current limit on the power supply so ir2101 short circuit current never exceeds 5A.
