DRV8316: Can a 3.3V provide by a external converter be connected to VREF/ILIM pin?

Part Number: DRV8316

Tool/software:

Hi,

As AVDD is 3.3V, external voltage for VREF must be lower than 3.3V for some headroom(to consider AVDD 3.3v output accuracy) . Is it right?

Hi Ken,

You are correct, VREF should not exceed AVDD so having VREF at 3V would be a good option but you can also use AVDD to supply VREF?
