Multi-chemistry charger in a 20-VQFN package
The Texas Instruments BQ24115RHLRG4 is a bqSWITCHER™ series multi-chemistry battery charger IC designed for 1 to 3 series cells. It delivers a programmable constant charge current up to 2A from a supply rail rated to 16V.
Charge current and programmable features
Maximum charge current is 2A, set via an external resistor. The charger supports constant-current/constant-voltage (CC/CV) profiles and includes programmable charge current and timer features — the timer provides a safety termination if the battery does not reach full voltage within the set window. Fault protection includes over-temperature and over-voltage monitoring, reducing the need for external supervisory ICs.
The BQ24115RHLRG4 is listed as obsolete by Texas Instruments. No official replacement part number is recorded in the lifecycle data.
