Hi all,

please Clarify whether TA_TMP_DETECT_B and TA_BB_TMP_DETECT_B  are effectively used in LS1046ARDB. if used, they should have 1K pulldown resistor. If not, they must be pulled high through 2-10K to their respective voltage. it seems, none of these is done in RDB. Please clarify.

Thanks in Advance!

TA_TMP_DETECT_B and TA_BB_TMP_DETECT_B are not used in LS1046ARDB. Both these pins are pulled up, first via 1K resistor, other one directly connected to 1V. These pull-ups are slightly different than in recommendations, but also acceptable.

Regards,

Bulat
