Texas Instruments BQ24400 Switch-mode NiCd/NiMH Battery Charger with Peak Voltage Detection Termination BQ24400D

The BQ24400D is a programmable monolithic integrated circuit designed for fast-charge management of nickel cadmium (NiCd) and nickel metal-hydride (NiMH) batteries in both single and multi-cell configurations. It features a high-frequency switching controller that enables efficient charger designs. The device includes multiple charge termination criteria such as peak voltage detection, maximum temperature, and maximum charge time, ensuring safe and effective charging. Additionally, the BQ24400D supports pre-charge qualification to detect shorted, damaged, or overheated cells, and offers a programmable trickle-charge mode for conditioning deeply discharged batteries. It also includes a sleep mode for low power consumption and built-in detection for battery removal and insertion. The device is available in an 8-SOIC package and operates within a temperature range of -20¬8C to 70¬8C. This product is suitable for applications requiring reliable battery management in various electronic devices.
