DRV8846: Need to check the Rdp Resistor of DRV8846

Part Number: DRV8846

Hi 

My customer would like to check the Rpd max and min value of DRV8846. The datasheet only shows the typical value of this parameter. 

Thanks!

    Hisen,

    The minimum pulldown resistor value is more important than the maximum pulldown resistor value for calculating the maximum pullup resistor value.

    Iih current is listed as 30uA maximum, which translates to a 5V/30uA= 166.7kOhm resistor.
