Part Number: BQ2970
Dear Experts,
We are looking for a single-cell lithium battery protection IC and hope its OVP voltage is about 4.15V, from the BQ29700 datasheet I see that Vovp is 4.275V, and BQ297xy seems to be Vovp programmable, but I can't find…
Part Number: BQ2970 Other Parts Discussed in Thread: BQ2982 , Hi team,
I want to check with you:
What is the difference between V0CHG and V0INH?
Is that the V0CHG means the charger voltage needs to large than 1.7V?
and the V0INH means the battery voltage…
