Part Number: DRV8873

Hi team,

 DRV8873 is supporting High-side recirculation (brake) in datasheet Figure 10.
 The customer is concerned about noise to the power supply line, because the power supply is not so strong.

  1.Is it possible to support low side recirculation (brake)?
  2.If it is difficult to support low side recirculation, is there the solution not to impact power supply line? 

Regards,
Ogasawara   

  • Hi Ogasawara-san,

    1.Is it possible to support low side recirculation (brake)?

    Low side recirculation is possible in independent mode. Please refer to Table 6 in the datasheet.
    Also please note that OLA (open load active) does not operate properly (section 7.3.2.4.2)
