3 Description
The BQ25960H 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 BQ25960H 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.
