DRV2605L: Question for DRV2605L

Annie Liu

Part Number: DRV2605L

Hi Team,

VDD power supply is 3.3V, can I2C use 1.8V pull-up? If yes, does the circuit need to be configured? Introduced on the datashee that 1.8V compatible, VDD withstand voltage digital interface, is it compatible with 1.8V I2C interface?

Thanks,

Annie

Hi, Annie,

The DRV2605L is tolerant to 1.8V interface and it can be up to VDD level. This means that it can be pulled-up to supplies from 1.8V to VDD.

There's no need to add additional circuitry.

Best regards,
