The extra diodes across the gate resistors is ir2101 adding to ir2101 capacitance problem as well as adding a switching delay and a path from the switching transient voltages to ir2101 back to the device. Some conflicting advice here.
I will test ir211 week ir2101 give feedback on whether this solves the problem. An Introduction to Infineon Gate Drivers www.

The spike will be proportional to the current, which is ir2101 it only blows at high current. However latest ir2101 occured on two drivers at once – the one closest to the 48v connector and the one furthest away.
Watch our introduction video and become familiar with our product portfolio. Ir2101 just curious, considering that I do have deadtime and I’m not currently trying to optimize ir2101 throughput yet – does ir2101 high resistor values pose ur2101 other problems? My tests only confirm that higher resistance increases turn on time. The gate resistance is way to high ohms, the parallel resistors R17 and R18 are not supposed to be there, as they ir2101 spoil the performance of the bridge.
However one of those capacitances can go to ir2101 48V value as the bridge switches. Post as a guest Name. The datasheet ir2101 specifies mA negative current but I ir2101 quite understand what that means.
Will try this definitely for my next test. Is it the current generated when gate is ir2101 I’m using 3x of these circuits to drive a BLDC motor ig2101 0. Infineon welcomes your ir2101 and questions.
ir2101 The application note AN was very helpful as well: Questions Could there be an issue with ir2101 smaller capacitor besides slower turn on times? Hopefully you have measured the turn on and turn off times and are using at least double that value. Ok, ir2101 seems we are on to something here. I have also reduced the gate series i2r101 to 36Ohm.
At first it happened twice ir2101 the driver furthers away from 48v connector. I have seen schematics using resistors. The motor spins up to a certain point, then as I increase the motor speed current increases as well one or more of the drivers fail.
Bogumil I’ve never seen such configuration. Ir2101 diodes are for delaying turn on ir2101 making sure turn off is very fast.
Also, your last two suggestions: Not sure if the diodes D8 and D9 without a series resistor are OK. You say you are already doing that so it is good. Martin Datasheet absolute max. Summary of working solutions So far adding bypass caps on 48v rail seems to be the solution I added one 47uF 50V electrolytic and ir2101 0. Ir2101 it is driving back into whatever is supplying that rail it can cause ir2101 rather unfortunate effects.
If you have any questions concerning our products, please fill out ir2101 following form. Datasheet says that driver is operational up to V switching ir2101. My reason for R17 and R18 is as pull ir211 resistors to pull the gate down to make sure it doesn’t ir2101 come on from ir2101 if the driver happens not to drive it.
