TMAG5273: Issue putting sensor in sleep mode (to much current consumption)

Part Number: TMAG5273

Hi, I would like some help putting the sensor to sleep.

I'm writing to the register 0x01 the value 0x01, meaning that the mode should be sleeping.

There is in fact some reduction in power, but the datasheet says around 5nA, but i'm getting a consumption of around 450 uA. 

Is there something that i'm missing?

Thank you,

    Fabio,

    Thank you for reaching out with your question.  Based on the current measurement you report, the device seems rather that it is likely only in Stand-by mode. Could you share you device configuration prior to setting the sleep mode register and the details of how you setup your test?

    Thanks,

    Scott

    Hello Scott, 

    Thank you for the answer, I think that I might have found the problem.

    I have the INT pin connected directly to GND, I'm not intending to use it, and for that I need to mask the INT.

    Now, before trying to go to sleep I'm masking the interrupt and it is working.
