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 proces.
1
• 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
• Fast-Charge Termination by ΔT/Δt for Nickel Chemistries, Minimum Current for Li-Ion Chemistries, Maximum Temperature, and Maximum Charge Time
• Selectable Top-Off Mode for Achieving Maximum Capacity in NiMH Batteries
• Programmable Trickle-Charge Mode for Reviving Deeply Discharged Batteries and for Postcharge Maintenance
• Built-in Battery Removal and Insertion D.
