Part Number:DRV8814
In the test, it is found that nFault will protect the DC motor when it starts, which causes the motor to not rotate properly, and the phenomenon repeats when it is re-energized.
Testing power supply V_MT, no abnormalities (higher than 8V) were found. Please help to analyze the reason why DRV8814 can not properly drive the motor to rotate.
