DRV777: different logic level input

Mia Ma

Part Number: DRV777

Hi team,

Here is an application of DRV777 want to double confirm with you.

I am using DRV777 for relay driver; but I have a diifferent logic voltage level but the same GND, which is 2.5V and 3.3V.

So if above application could be acceptable? Anything special need to pay attention to?

Thanks.

Best regards

Hi Mia,

Yes, you can use 2.5V and 3.3V as long as they are referenced to the GND pin of the device. The GND pin and the common board GND should be tied together to ensure both GNDs are similar and there is no offset.
