The bq2000T 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 bq2000T 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 bq2000T provides a number of charge termination criteria:

  • Rate of temperature rise (ΔT/Δt) (for NiCd and NiMH)
  • Minimum charge current (for Li-Ion)
  • Maximum temperature
  • Maximum charge time

For safety, the bq2000T 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 bq2000T uses trickle-charge to condition the battery. For NiMH batteries, the bq2000T provides an optional top-off charge to maximize the battery capacity.

The integrated high-speed comparator allows the bq2000T to be the basis for a complete, high-efficiency battery charger circuit for both nickel-based and lithium-based chemistries.
