  RE: DRV8323: Why PWM GHx out from DRv8323s has a platform and the phase current is almost unchanged?

  Dear Adam: A good news is that we have solved the problem and the offset is working. Thank you very much for your help. SO_U in the circuit is as follow, the problem is caused by pin configuration in software. Yours sincerely Best wishes！

  RE: DRV8323: DRV8323 shoot-through with small MOSFETs

  Karsten, Thanks for posting on the MD forum! The DRV8323 sets the IDRIVE to maximum by default which will attempt to drive your very small 1.6nC Qgd with 1A source and 2A sink. This is likely causing the partial shoot-through as the gates will ring...

  RE: BLDC motor drive IC with integrated current sensing

  Subbaraju, Thanks for posting on the MD forum! The integrated current sensing, do you mean a current shunt amplifier? Is it okay for the sense resistor and FETs to be external? For the MC33035, you should check out the DRV8323, this is our 60V gate...
