Description

The BQ2000SN-B5G4 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 BQ2000SN-B5G4 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 BQ2000SN-B5G4 Features • Safe Management of Fast Charge for NiCd, NiMH, or Li-Ion Battery Packs• High-Frequency Switching Controller for Efficient and Simple Charger Design• Pre-Charge Qualification for Detecting Shorted, Damaged, or Overheated Cells• Selectable Top-Off Mode for Achieving Maximum Capacity in NiMH Batteries• Built-in Battery Removal and Insertion Detection• Sleep Mode for Low Power Consumption BQ2000SN-B5G4 Applications • Multi-Chemistry Charger• Nickel Charger• High-Power, Multi-Cell Charger
