Hi, Support Team

Sorry to bother you.

We would like to use TMP1075 to replace Onsemi NCT75MNR2G
If we don't change the software FW control, is the read out value will be same as NCT75?

or another part number suggestion?

if any, Please advise me.

Thanks,

Best regards,

    Dear Lawrence -

    The two devices are slightly different, looks like the competitive part is not like the other LM75/TMP75/TMP1075 (industry standard devices) - if they are using one-shot mode, they will need to change their firmware slightly to make it correct as that device has a one-shot register (0x04) which does not exist in any of the other devices.
