INA233: I2C Bus Clear

Shuhei Goto
Expert 6540 points

Part Number: INA233

Hi team,

Could you support following question please?

[Q1]
Does this device support Bus Clear as defined in the I2C bus specification?
Also, does the bus clear process initialize the registers?

[Q2]
Are the registers initialized by Power-On Reset (POR) in this device?

Best regards,
Goto

    Hello Goto-san,

    Here are my responses to your questions:

    [Q1]

    Yes, we refer to this in the datasheet as "timeout". SMBus timeout in the INA233 resets the interface whenever SCL is low for more than 28ms.

    This does not change any register values.

    [Q2]

    Power-On Reset sets all registers back to the default setting.

    Regards,

    Mitch
