The BQ25960 is a 98.1% peak efficiency, 8-A battery charging solution using switch capacitor architecture for 1-cell Li-ion battery. The switched cap architecture allows the cable current to be half the charging current, reducing the cable power loss, and limiting temperature rise. The dual-phase architecture increases charging efficiency and reduces the input and output cap requirements. When used with a main charger such as BQ2561x or BQ2589x, the system enables full charging cycle from trickle charge to termination with low power loss at Constant Current (CC) and Constant Voltage (CV) Mode.

The BQ25960 supports 5-A Bypass Mode charge (previously called battery switch charge) through internal MOSFETs. The Rdson in Bypass Mode charging path is 21 mΩ for high-current operation. The integrated Bypass Mode allows backward compatibility of 5-V fast charging adapter to charge 1-cell battery.

The device supports dual input configuration through integrated mux control and driver for external N-FETs. It also allows single input with no external N-FET or single N-FET.

The device integrates all the necessary protection features to support safe charging, including input overvoltage and overcurrent protection, output overvoltage and overcurrent protection, input undercurrent and reverse-current protection, temperature sensing for the battery and cable, and junction overtemperature protection in both Switched Cap and Bypass Mode.

The device includes a 16-bit analog-to-digital converter (ADC) to provide VAC voltage, bus voltage, bus current, output voltage, battery voltage, battery current, input connector temperature, battery temperature, junction temperature, and other calculated measurements needed to manage the charging of the battery from the adapter, or wireless input, or power bank.
