1.Using the STSPIN4G chip, after enabling the timer output, an error message will be reported stating a short circuit and the motor will not run.
2.The upper arm of the entire bridge MOS is conductive, while the lower cliff is disconnected. Want to know the reason for the short circuit? As shown in the figure. The input voltage of my SCREF pin is 3.2V, which is simulated using DAC output; There is a 1K resistor connected between the SCREF and DAC pins, and I don't know what the impact is? I have set the voltage to 3.2V, and the VDS protection should have been disabled.
3.Secondly, I burned the same code into EVSPING4 and the board did not report any errors.
