BQ25980
Description
The BQ25980 is a 98.6% peak efficiency, 8-A battery charging solution using dual-phase switched cap architecture for 2-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.
Key Features
- 98.6% peak efficiency switched cap parallel charger supporting 2-cell battery and 8-A fast charge
- Integrated 7-A bypass mode fast charge – 13mΩ charging path resistance for high current operation
- Dual-input power mux controller for source selection
- Parallel charging with synchronized dual BQ25980 operations for up-to 12-A charging current
- Programmable settings for system optimization – Interrupts and interrupt masks – ADC readings and configuration
- Integrated 16-bit ADC for voltage, current and temperature monitoring
