Part Number: DRV8818
Other Parts Discussed in Thread: DRV8803, DRV8844, , DRV8811

Hi team,

My customer is using DRV8803, DRV8844 and DRV8818. We want to check why the DRV8818 logic pins internal pull down resistor is 1Mohm, but the DRV8844 and DRV8803 internal pull down resistor is 100kohm. Thanks.

BR

    Hi Frank,

    The DRV8818 is a higher current version of the DRV8811, one of the first devices in the portfolio. The DRV8811 and DRV8818 have similar pulldown resistor values of 1 MOhm. Over time, the pulldown resistors were changed to provide more noise immunity.
