Hi Higa,

When not using the remote sensor with the TMP441/42 the DXP and DXN inputs must be connected together to prevent meaningless fault warnings.

Please see Sensor Fault sections of the datasheet for more details.

Thanks,

David

Hi David-san

Thank you for prompt reply.

I have an additional question.

Can DXP and DXN connected together remain open without connecting to GND or VCC?

Best regards,

Higa

Hi Higa-san,

Yes that is the intention. DXP and DXN pins are connected together and not connected to any other net (including VCC or GND).

Thanks,

David
