Part Number: BQ27Z561-R1 Dear expert,
If AMB_PRED=0, TAmbient will be updated only in relax mode, right? How often? Every 5s? Or just once.
Is TAmbient taken by average of temperature()? Or just one point temperature?
In customer circumstance, they find…
Part Number: BQ27Z561-R1 Dear expert,
"This can be useful in system applications that experience large increases in ambient temperature during discharges and/or charges without entry to RELAX mode."
So for this situation, I should enable AMB_PRED…
