BQ25980 - 8-A Switched Cap Parallel Battery Charger

General 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.
  • Patent pending dual phase switched cap architecture optimized for highest efficiency.
  • Input voltage is 2x battery voltage (7.0V to 9.54V).
  • Output current is 2x of input current (up to 4.75A).
  • Reduces power loss across input cable.
  • Integrated 7-A bypass mode fast charge.
  • 13mΩ charging path resistance for high current operation.
