Switch-mode Multi-Chemistry Battery Charger With Peak Voltage Detection Termination

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 detects the battery chemistry 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 charging current (f or Li-Ion) Maximum temperature Maximum charge time For safety, the BQ2000 inhibits fast charge until the battery voltage and temperature are within user-defined limits. If the battery voltage is below the low-voltage threshold, the BQ2000 uses trickle-charge to condition the battery. For NiMH batteries, the BQ2000 provides an optional top-off charge to maximize the battery capacity. The integrated high-frequency Comparator allows the BQ2000 to be the basis for a complete, high-efficiency power-conversion circuit for both nickel-based and lithium-based chemistries.
