To do it well you really need to add another push-pull stage NPN-PNP in between at which point you are really ramming a square peg into a round hole Should Ir2101 decouple each FET or each pair?
Summary of working solutions Ir2101 far adding bypass caps on 48v rail seems to be the solution I added one 47uF 50V electrolytic and 2 0.
Martin Don’t remove R17 and R The theory is good, but they ir2101 don’t have enough oomph to quickly switch bigger capacitance gates. Ir2101 have added them to the schematic afterwards. Ir2101 agree to the usage of cookies when you continue browsing this site. I’d add electrolytic caps too, the one you put in your layout seems in the proper place.
IR High and Low Side Driver IC
However one of those capacitances can go to the 48V value as the ir2101 switches. The ir2101 are for delaying turn on and making sure turn off is very fast.
My reason for R17 and R18 is as pull ir2101 resistors to pull the gate down to make sure it doesn’t accidentally come on from disturbances if the driver happens not ir2101 drive it. Add low-ESR ir2101 swith ripple current rated for the motor current.
You ir2101 not shown how you are dealing with the fly-back currents in the above schematic, or shown how the motors are connected or your grounding system. I have also been using 0. Hopefully you have measured the turn on and turn off times and ie2101 ir2101 at least double ir2101 value.
The application ir2101 AN was very helpful as well: If I decouple each FET then that would mean the cap would be placed between drain and source of each fet. Would ir be a better driver ir2101 for ir2101 mosfets?
Martin Yes ir2101 flyback diodes do protect the mosfets, however you also have to take into account where the current goes after ir2101. An Introduction to Infineon Ir2101 Drivers www. I will test next week and give feedback on whether this solves the problem.

I have enough dead time to make sure gates do not short. If 48V is not properly bypassed then of course everything will blow due to voltage ir2101 caused by energy stored in wiring inductance having nowhere to go. I have a few theories about what may be the ir2101 but I have not been able ir101 ir2101 exactly what it is because I think it has something to do with a transient condition that happens very quickly not giving me enough time to see it on the scope.
I’m using 3x of ir2101 circuits ir2101 drive a BLDC motor with 0.
Can the above circuit work at all ir2101 do I have to completely redesign it?
