Hi @RJ_0701 ,

For the given command “BDRV_Set_Bridge(Ch_En, Ch_Off, Ch_En, Ch_Off)” all the MOSFETs are off. Here LS1 and LS2 driver circuits are on but the corresponding MOSFET are still off.

Best Regards,
Sahil Kumar

Hi @RJ_0701 ,

Here we can see you want to break the motor using the lower Mosfets of the full bridge. Whenever the break is applied using upper/lower Mosfets you will observe the back emf current as it is the reason behind the opposition of the motor rotation and quickly stopping the motor.

To apply the brake to the motor you can also use BDRV_Set_Bridge(Ch_On, Ch_En, Ch_On, Ch_En).
Note: You will always have the back emf current while braking the motor.

Best Regards,
Sahil Kumar

Thank you for your explanation, its very much clear  , but what will use of below setting  will consider all mosfet as off ? (Ch_en, Ch_off, Ch_en, Ch_off)
