Multi-chemistry charger for 1-4 cells in 8-TSSOP
The Texas Instruments BQ2000PWR is a multi-chemistry battery charger IC supporting 1 to 4 cells in series, with constant programmable charging current.
Programmable charge parameters and chemistry flexibility
The IC accepts programmable current, timer, and voltage thresholds, allowing the designer to tailor the charge profile for Li-Ion, NiMH, NiCd, or other chemistries without external microcontrollers. With a 1 to 4 cell count range, it fits portable devices, medical instruments, and industrial handhelds where a single charger IC must handle different battery packs.
