Part Number:DRV8320
Test Conditions:
System VCC 14V
Mode pin connect to Gnd
Idrive pin connect 18K to VCC 3.3V
VDS pin connect to VCC 3.3V
Use 6x PWM do 6-step block commutation spin function (reference below table), DRV8320H immediately damage for just start spin motor .Replace new one test again still damage .Please help to comment on this, thanks !
