BQ2002CSNTR Description

Short technical summary and product information.

The BQ2002CSNTR from Texas Instruments is a versatile battery charge controller IC specifically designed for reliable charging of Nickel Cadmium (NiCd) and Nickel-Metal Hydride (NiMH) battery applications. This device integrates fast-charge capabilities with pulsed-trickle control, making it suitable for charging one or more battery cells.

 

Key electrical specifications include a maximum charge current of 2A, an input voltage range from 4V to 6V (absolute maximum 7V), and a battery charge voltage range of 0V to 6V. The BQ2002CSNTR supports multi-chemistry battery packs and features thermistor monitoring for battery temperature.

 

Packaged in an 8-SOIC surface-mount case, the BQ2002CSNTR operates within a temperature range of 0°C to 70°C. Its control interface is standalone and RC-settable. The IC offers fast-charge termination through various methods including negative delta voltage (dV), maximum voltage, maximum temperature, and maximum time.

 

This product is currently in the process of being discontinued. Designers should consider alternate solutions for new projects.
