BQ51010B: LiPo 3,7V battery charge

Part Number: BQ51010B

I want to charge a small LiPo battery of 3,7V. Can it be charged with the BQ51010B component? As I can see, the output voltage options are around 4,2V.

1 - How the component can notice that the battery is completely charged at 3,7V?

2 - How the component will stop charging the battery?

3 - How the charging ending can be notified? I see that CHG can do that, but as long as I have test it, CHG is always high (both charging or not)

Thank you so much in advance,

Gerardo

  • The BQ51010B is a 7V power supply and cannot directly charge a battery. Battery charger application is shown in data sheet figure 37.

    A direct battery charger is the BQ51050B.
