Product details

The Texas Instruments BQ24130RHLR is a multi-chemistry battery charger IC that handles 1 to 3 series cells, accepting a supply up to 17 V. It delivers a constant programmable charging current — set by an external resistor — and includes over-temperature and over-voltage fault protection. The part is suited for portable equipment, power tools, medical devices, and industrial handhelds where the battery chemistry may vary between Li-ion, Li-Po, or LiFePO4, and where the ambient temperature range spans -40°C to 85°C.

ROHS3 compliant, so it meets current European and global restrictions on hazardous substances.

Frequently asked questions

How does BQ24130RHLR compare to BQ24133?

The BQ24133 is a higher-integration sibling that adds dynamic power-path management (DPPM) and a separate system output, allowing the load to run from the input supply when available while charging the battery. The BQ24130RHLR lacks power-path management — the battery and load share the same node. Choose the BQ24133 if the application needs instant-on with a deeply discharged battery or independent system regulation; the BQ24130RHLR is the simpler, lower-cost option when power-path is not required.

Is BQ24130RHLR compatible with LiFePO4 batteries?

Yes. The BQ24130RHLR is a multi-chemistry charger, so it can charge LiFePO4 packs. The termination voltage for LiFePO4 (typically 3.6 V/cell) is set by the external resistor divider on the VCELL pin — the datasheet application circuit shows how to program the target voltage for 1 to 3 cells.

How to program charging current on BQ24130RHLR?

Charging current is set by a single resistor from the ISET pin to ground. The relationship is linear: I_CHG (A) = V_ISET / (R_ISET * K_ISET), where V_ISET is typically 2.5 V and K_ISET is a fixed gain factor. The datasheet provides a table of standard resistor values for common charge currents.
