BQ2000 具有峰值电压检测终端的多化合物、开关模式充电管理 IC

BQ2000 描述

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:

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-speed comparator allows the bq2000 to be the basis for a complete, high-efficiency battery charger circuit for both nickel-based and lithium-based chemistries
