BQ24400 Description

Short technical summary and product information.

The Texas Instruments BQ24400 is a programmable, monolithic integrated circuit designed for the fast-charge management of nickel cadmium (NiCd) and nickel metal-hydride (NiMH) battery packs. It is suitable for single or multi-cell applications and offers a high-frequency switching controller for efficient charger design.

Key features include a maximum charge current of 2A, an input voltage range of 4V to 6V, and an operating temperature range of -20°C to 70°C. The device supports various charge termination criteria such as peak voltage detection (PVD), maximum temperature, and maximum charge time. It also includes pre-charge qualification for detecting shorted or damaged cells, a selectable top-off mode for NiMH batteries, and a programmable trickle-charge mode for reviving deeply discharged batteries.

The BQ24400 is available in 8-pin DIP, Narrow SOIC, or TSSOP packages. Its design facilitates simple and efficient battery charger circuits for nickel-based chemistries, making it suitable for applications like general nickel chargers and high-power, multi-cell chargers.
