• UCC5390: Controlled power to a Motor drive Circuit - issues

  

  Lingamurthy Komire

  Part Number: UCC5390 Hi, I have been working on the above circuit design. It is an application of motor driving based on MOSFETs ( STW70N60M2 ) and Gate drivers ( UCC5390SCDR ). Motor power is fed to the drive circuit (M3 and M4) through an another MOSFET…
