The BQ2000TSN from Texas Instruments is a versatile, programmable, monolithic IC for fast-charge management of NiCd, NiMH, or Li-Ion battery packs. It automatically selects the appropriate battery chemistry and employs optimal charging and termination algorithms to prevent undercharging or overcharging.
Key features include fast-charge termination by ΔT/Δt for nickel chemistries and minimum current for Li-Ion, along with maximum temperature and charge time limits. It also offers selectable top-off mode for NiMH batteries and a programmable trickle-charge mode for reviving deeply discharged cells or post-charge maintenance. Built-in battery removal and insertion detection, along with a sleep mode for low power consumption, enhance its functionality.
This IC is housed in an 8-pin SOIC package and operates within a temperature range of -20°C to 70°C. It is suitable for multi-chemistry and high-power, multi-cell charger applications.
Note: This part is not recommended for new designs.
