TIDA-010056: TIDA-010056

Hello TI Helpers,

We are getting voltage only MOSFET connected on phase B and phase C, we are not getting voltage across MOSFET of phase A. We have given 24V to VM pin of driver IC (DRV8353RH).

Thank you in advance.

    Hi, 

    I just assumed that your connections were correct. Please double check your connection following the UG.

    Please rotate the motor to change the hall input and check the phase output without connect to motor. If phase A still has no output, it may be broken. You can measure the resistance for MOSFET to check if the FETs was broken. And also, please check if the phase A driver output is correct or not. if no output from driver, maybe driver was broken.
