Product Overview

The BQ2000SN-B5 is a programmable Monolithic IC for fast-charge management of nickel cadmium (NiCd), nickel metal-hydride (NiMH), or Li-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. 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, it 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.
  • Safe management of fast charge for NiCd, NiMH, or Li-ion battery packs
  • High-frequency switching controller for efficient and simple charger design
  • Programmable trickle-charge mode for reviving deeply discharged batteries
  • Built-in battery removal and insertion detection
  • Sleep mode for low power consumption
  • Green product and no Sb/Br
Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
