Part Number: BQ25708 Hi,
I have a design based on the BQ25708 chip which is meant to be able to charge 2s and 4s batteries. Additional circuitry has been implemented to determine whether 2s or 4s charging is required, and a microcontroller applies the…
Part Number: BQ25708
We have a product that has incorrectly connected a voltage divider circuit (2 resistors) from a 12 volt battery to the CELL_BATPRESZ pin. If the battery is depleted at power up, the CELL_BATPRESZ pin is too low and the SYSOVP threshold…
