Regarding DRV110EVM, the hold current changes when the input voltage is changed.

The higher the Vin, the higher the hold current.

According to the datasheet, it stated the current is determined by Rpeak value.

Could you please see the waveform below let us know why the hold current changes.

DCSupply 13V

DC Supply 14V

I appreciate your great help in advance.

Best regards,
