If VBAT is below 4.2V, VBUS is only limited by the lower of ILIM pin resistor or IINDPM setting which should be 3A if PSEL is low, unless VBUS has dropped below the VINDPM threshold. With input current...

Betty, Yes. As long as VIN stays below VBAT_OV, the charger can charge multiple cells. The single cell comment refers only to LiIon.

View ArticleForum Post: RE: BQ25713: Advice on 4S4P Battery to charge
Hi Mo, The bq25713 and the bq24610 are both capable of charging your battery. We only count the number of series cells, so a 4s4p battery is 4 cells, not 16. The number of series cells determines the...

Hi Imran, There is no mode where CAP1 is on but REGOUT is off. Suggestions would be: Check that REGOUT is not shorted. You have done this. Check that REGOUT is not overloaded. Did you measure the...

Hi Imran, It would seem you do not have good connections to cells or if you are using a power supply you may not have a cell simulator. Use resistors to divide the supply voltage to provide each cell...

Hi Imran, The schematic appears blurry, but I don't see a problem with REGOUT. Check for a short across the capacitor or between the pin and ground, or elsewhere on the net. If a high voltage was...
