Product details

Single-cell Li-Ion linear charger with programmable current and timer

The Texas Instruments BQ24202DGNR is a linear charger IC for single-cell Lithium Ion or Lithium Polymer battery packs, delivering a constant-current charge up to 500 mA maximum. It operates from a supply up to 13.5 V and integrates over-temperature and short-circuit fault protection, reducing the external component count for a compact charger design. The charge current and charge timer are programmable via external components, giving the designer control over charge rate and termination timing.

Frequently asked questions

Does BQ24202DGNR have thermal protection?

Yes, the BQ24202DGNR includes over-temperature and short-circuit fault protection as built-in features, which help safeguard the battery and charger circuit during fault conditions.
