Programmable Multi-Chemistry Fast-Charge Management The bq2000 is a programmable, monolithic IC for fast-charge management of nickel cadmium (NiCd), nickel metal-hydride (NiMH), or lithium-ion (Li-Ion) batteries in single- or multi-chemistry applications. The bq2000 chooses the proper battery chemistry (either nickel or lithium) and proceeds with the optimal charging and termination algorithms. This process eliminates undesirable, undercharged, or overcharged conditions, and allows accurate and safe termination of fast charge Depending on the chemistry, the bq2000 provides a number of charge termination criteria: • Peak voltage, PVD (for NiCd and NiMH) • Minimum charge current (for Li-Ion) • Maximum temperature • Maximum charge time For sa... |
