DRV8813: Difference between DRV8812 and DRV8813 in internal circuit

Part Number: DRV8813
Other Parts Discussed in Thread: DRV8812,

Hello E2E,

I compared for DRV8812 and DRV8813 in them datasheet.
On pin function table, DRV8813 has "internal pulldown" for control pin.
There is no description of "internal pull-down" in the data sheet of DRV 8812.

Question;
 - Are the internal control circuits of these devices different?

Regards,
ACGUY

    ACGUY,

    DRV8812 also has the "internal pull-down" . According to an EVM board measurement result, both AENBL and BENBL pins have 50kohm internal pull-down resistor. You can also treat the internal control circuit logic as same if the datasheet gives the same function description.
