Part Number:DRV8302
Hello! I am working with DRV8302 and sometimes i have a little trouble. IC goes fault mode (nFAULT pin is low) and reset sequense of EN-Gate (high > low > high for about 10 or 20 us) cant make a reset of IC. I must note that a im using DRV8302 in DC mode (not BLDC) and one half-bridje is free, so i suppose it to be a reason of my trouble. So i have two questions, what exact sequense of EN-Gate can reset IC while Fault condition presents and what possible reasons of PVDD and GVDD underoltage or overvoltage faults. Osciloscope nothing shows me about power deviations. Also i attached the part of my schematic and board file. Thanks!!!
