Original question:

INA230: Power sequence Analog inputs between and Vs

INA230: SCL Absolute Maximum Rating?

cfranAND
Prodigy 110 points

Part Number: INA230
Other Parts Discussed in Thread: INA226, INA231,

Tool/software:

On the datasheet, there are descriptions of absolute maximum ratings;
SDA : GND – 0.3 to +6
SCL : GND – 0.3 to VS + 0.3

There was a forum post 6 years ago that said the SCL rating is probably a typo and should be same as SDA: GND – 0.3 to +6 (and there is no clamp diode from SCL to VS).
Can TI confirm or deny?

    Hello,

    Yes, you are correct. It looks like this was fixed on the INA231 datasheet, but not the INA230 or INA226 datasheets. I will put in a request to have this corrected on the INA230 and INA226 datasheets. The SCL can be powered up without power on the device, similar to the SDA pin.

    Regards,
