Part Number: BQ25071 Tool/software: Hi, I am using one of using one of the design my predecessor has designed for BQ25071 LiFePO4 battery charging. We would like to use 1000mA battery for charging.
Can you review this circuit design. As far as testing…
Part Number: BQ25071 Other Parts Discussed in Thread: BQ28Z610 , BQ28Z620 Hi Team,
I have a couple of questions regarding BQ25071:
Does have any suggestions for the rare discharge application (e.g. emergency lighting where the LiFePo4 Battery is only…
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.
When supplying the BQ25071 with output from a solar harvester, the load introduced when the BQ25071 turns on (VIN rises…
