  • BQ25170: For 4.28V charge

    Part Number: BQ25170 Hi, I found BQ25170 VSET table as below. If I need 4.28V charge, does it possible to adjust VSET resistor to maybe 25k? or it fixed 4.2 or 4.35? Or any similar charger can support 4.28V charge for LiFePO4? Thanks! Jeff

  • BQ25170: Iset RC Filter at low charge current (10mA): how to design?

    Part Number: BQ25170 In our application, the charge current has to be 10mA. datasheet bq25170: For charge currents below 50 mA, an extra RC circuit is recommended on ISET to achieve more stable current signal. I didn't find a schematic and calculations…

  • RE: BQ25170: Question about the re-charging

    Lumina Gui said: That is, w hen the battery is fully charged, remove the adapter and re-plug it in. There will be a charging current of about 54mA, which will last for one night. 54mA is pre-charge current, 20% of Fast Charge. R-ISET = 1100 ohms will set…
