DRV2624: DRV2624 I2C pullup resisters

Akihisa Tamazaki

Part Number: DRV2624

Hello team,

My customer has a question about I2C pullup resisters of DRV2624.

In customer case, I2C pins of DRV2624 may be float condition (no pullup resisters) when the I2C comunication stop. Does this condition have problem or not?

Your help would be so appreciated.

Tamazaki-san,

The I2C resistors are only required when the I2C commands are sent. If the DRV2624 has been programmed and the I2C activity is not required anymore, the I2C resistors may be left floated. I just recommend to ensure that the registers has been programmed before leaving the I2C lines floated.

Best regards,
