INA3221: INA3221 Power Valid

Part Number: INA3221

Hi Expert,

The Power-Valid Upper-Limit Register default value is 10.00V and Power-Valid Lower-Limit Register default value is 9.00V during power on reset.

If we change PV limit register value for current design (12V, 3.3V, 1.8V), then this value can be asserted after setting complete until power on/off again.

Am I right?

thanks,

Mark Chen

    Mark,

    Thank you for using the forum to get your question answered.

    After a power on reset or a software reset there would be there reason to update the PV limit registers as the registers return to the default values.  Please be aware there is only one Power_Upper_Limit and one Power_Valid_Lower_Limit and applies to all your 3 bus voltages.
