Part Number: DRV8847

Hi Team,

Could you please let us know Min and Max value of VTRIP TA=-40℃ to 85℃?

Because, we would like to know the error of ITRIP without RSENSE.

I understand that Min is 140mV and Max is 16mV.

Is my understanding correct?

Hello!

What do you mean without RSENSE? RSENSE is required for current regulation. Do you mean error assuming perfect tolerance on SENSE resistor?

If so, the 140mV to 160mV is correct and already specified over operating temp range which is -40C to 85C per datasheet.

Regards,

Ryan
