DRV8837: Delay time calculation for each mode

Part Number: DRV8837

Dear team,

May I double confirm with you about below delay time of each mode switch?

 Mode Switch

 Delay time 

Forward to Coast

output disable time: T8

Forward to Brake

output high to low: T12

Reverse to Coast

output disable time: T8

Reverse to Brake

output high to low: T12

Thanks.

Regards,

Ben

  • Ben,

    Please check the logic table and timing block diagram.

    For example: forward to brake: OUT1 from H to L. The IN2 has to be from L to H to result OUT1 from H to L. So, the timing from IN2 L to H to OUT1 from H to L (forward to brake )should be t10 which is also for the reverse to brake (IN1 from L to H, OUT2 from H to L).
