DRV8711 Pre-Driver Holding Current?

Other Parts Discussed in Thread: DRV8711

I have 221k resistors tied from the gate-to-source on the high and low side FETS, so i am wondering what is the "holding current" of the pre-drivers after their t_drive high-current pulse?

Hi BZ

The holding current is normally very weak with micro levels. I will check the spec of that holding current level and back to you later.

Thanks,

Hi BZ

Checked that DRV8711 can source 10mA or sink 50mA for the hold current. Not so weak.

So it should be fine to have these 211k resistors from gate to source.

Thanks.

Not weak at all. Thanks for the information!
