DRV8837 / Input logic low current

Hi,

The input logic low current is defined ±5uA(maz) on the datasheet.

However this value is too large for my customer.

(My customer is saying that this value is too larger than sleep current)

Is there any way to decrease this logic current?

   i.e.) To connect the series resistor 

Could you give any advice?

Best Regards,
