The battery pack voltage for a 2-cell configuration is 8.4 V (4.2 V per cell). Fault protection includes over-temperature and over-voltage, which shuts down the charger if the battery voltage or die temperature exceeds safe limits. Programmable features include charge current and a safety timer — the timer terminates charging if the battery does not reach full voltage within the set window, a useful safeguard for damaged or deeply discharged cells. Supply voltage maximum is 16 V, so the part can be powered from a 5 V USB rail or a 12 V wall adapter without an external pre-regulator. The base product number is BQ24113, and the 'A' suffix indicates a later revision — the BQ24113A variant is the current production device. For dual-source planning, the BQ24113 and BQ24113A are pin-compatible; the 'A' version typically has tighter regulation accuracy or improved transient response, but both share the same footprint and charge-current range.","metaTitle":"BQ24113ARHLT Li-Ion Charger IC, 2 A Max, 20-VQFN","metaDescription":"Texas Instruments BQ24113ARHLT bqSWITCHER™ Li-Ion/Polymer charger, 2 A max charge current, 1-2 cells, 20-VQFN (3.5x4.5).
