DRV8411A: Information about leak current flow through the VREF pin.

Tool/software:

Hi,

1. Does a leak current flow through the VREF pin? 

2. Does VREF have any effect when switching to low-power sleep mode? I would like to confirm whether the VREF pin must be powered off during low-power sleep mode.

3. According to Figure 8-6 in the datasheet, is it correct to say that the current sense may deviate by 35% at 0.1A?

Thanks,

Conor
