SLUSDC7A March 2020 – November 2020 BQ25306
The BQ25306 charges 1-cell or 2-cell Li-Ion battery with up to 3.0-A charge current from up to 17-V input voltage. A new charge cycle starts when the charger power-up conditions are met. The charge voltage programmed by external resistor divider at FB pin and charge current are set by external resistors at ICHG pin. The charger terminates the charging cycle when the charging current is below termination threshold ITERM and charge voltage is above recharge threshold, and device is not in IINDPM or thermal regulation. When a fully charged battery's voltage is discharged below recharge threshold, the device automatically starts a new charging cycle with safety timer reset. To initiate a recharge cycle, the conditions of charger power-up must be met. The STAT pin output indicates the charging status of charging (LOW), charging complete or charge disabled (HIGH) or charging faults (BLINKING).
