DRV8850: Minimum logic high voltage (1h, 2h) vs VCC

Expert 5920 points
Part Number: DRV8850


in our system the control logic voltage high can be max. 2.5V. The VCC that we have for DRV8850 is 5.5V.

Now, there's a requirement that the min. logic high voltage is 0.5Vcc, so in our case that would be 2.75V - slightly larger than what we can provide with 2.5V.

We tested this scenario and the device seems to respond to 2.5V logic voltage as a high - can we be sure though that it's going to be like that in mass production scale?
