Part Number: DRV8846

Could you please let me know the Max and Min value for the following Pulldown/up resistors?

My customer need those value for their IO design.

Thanks

Mukuno-san,

Just searched the previous e2e post: https://e2e.ti.com/support/motor-drivers/f/38/t/678285?tisearch=e2e-sitesearch&keymatch=DRV8846

the minimum values of the internal pull down resistors for all of the mentioned pins is 166kOhms, given the Vin = 5V and max input current being 30uA. The tolerance is about 32kohm/200kohm=16%

Since it is on the same silicon, I would give a same tolerance percentage for maximum value (232kohm) and pullup resistor (+/-16%).
