Product details

Multi-cell charger with I²C programmability

The BQ25672RQMR is a Texas Instruments I²C-controlled switch-mode battery charger for 1- to 4-cell Li-Ion or Li-Polymer packs. It delivers up to 3 A constant charge current from a supply up to 24 V, with programmable current and voltage setpoints via the I²C bus. Integrated fault protection covers over-current and over-voltage conditions, reducing external component count for the protection circuit.

Charge current and cell count range

Maximum charge current is 3 A, which sets the charging time floor for a given battery capacity. The 1- to 4-cell support means the charger can handle battery pack voltages up to 18.8 V — suitable for power tools, portable medical gear, or industrial handhelds with series-cell stacks.
