The BQ2000PN-B5 is a switch-mode multi-chemistry Battery Charger with peak voltage detection termination. 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 charger 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. The charger 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 charger uses trickle-charge to condition the battery. For NiMH batteries, the charger provides an optional top-off charge to maximize the battery capacity.

• High-frequency switching controller for efficient and simple charger design
• Pre-charge qualification for detecting shorted, damaged or overheated cells
• Fast-charge termination by peak voltage for nickel chemistries
• Programmable trickle-charge mode for reviving deeply discharged batteries
• Built-in battery removal and insertion detection
• Sleep mode for low power consumption
