They combine high-accuracy current and voltage regulation, battery conditioning, temperature monitoring, charge termination, bq2057 indication, and AutoComp charge-rate compensation in a bq2057 8-pin IC.
Battery Charge Voltage Max V.
How to used BQ2057 for 7.4V 4-Cells 4400mAh Li-Ion Battery?
Aug 30, Am using the BQW to charge a 2-cell Li-ion battery. I have used above circuit in my design. Content on this nq2057 may contain or bq2057 subject to specific guidelines or limitations on use.

The bq then charges the battery in three phases: Yes, we suggest you to place the diode inside the feedback loop to block leakage to SNS. Question, as it bbq2057 been awhile on the answer; is this still the preferred solution qb2057 eliminating the back feed voltage to VSUPPLY, inserting the isolation diode between the pass element and the battery?
It seems that you might have done the calculations incorrectly. All content bq2057 materials on this site are provided “as is”.
