Hello Ernest,
Assuming that the battery will get discharged fully twice a year, this should not be an issue. In this scenario you should get a Qmax update twice a year. Since you are using a LFP battery, they tend to degrade slower than other chemistries…
Hi Hien,
Sorry about the delay response, unfortunately I didn't get a notification for your reply.
Hien Van To said: If I connect the battery, and disconnect the load, VOUT = VBATT, but the IC doesn't charger the board.
What is the EN pin voltage…
Part Number: BQ25071-Q1 Other Parts Discussed in Thread: BQ25071 , , BQ25171-Q1 , BQ25170 1. There are differences in the SPEC values for some items in the datasheet. Is this the difference because the Q1 product has a wider operating temperature range…
Part Number: BQ25071-Q1 Other Parts Discussed in Thread: BQ25071 Figure 4. The OVP Threshold vs Temperature curve is slightly different. Why is it different between bq25071 and bq25071-Q1? <BQ25071> <BQ25071-Q1> Regards, Kagawa
Thanks Bill, I understand that now.
However, I would suggest reviewing the bq25071 datasheet where some of the statements are misleading.
For example, on page 3 in the Pin Functions table, the datasheet says "CHG is pulled low while the device is charging…
Part Number: BQ25071 Other Parts Discussed in Thread: BQ25170 , Client wants to be able to make LiFePO4 cell (likely 18650) field-swappable. If the user inserts the battery the wrong way around and tries to charge it with this charger, will the charger…
Part Number: BQ25071 Related to an earlier inquiry regarding the oscillation seen in the BQ25071, I have finally identified the issue.
