BQ2002D Description

Short technical summary and product information.

The BQ2002D from Texas Instruments is a low-cost CMOS battery charge controller designed for NiCd and NiMH battery applications. It provides reliable charge termination using dT/dt control and supports charging one or more battery cells.

Key electrical specifications include a maximum charge current of 2A, an input voltage range of 4V to 6V (absolute maximum 7V), and battery charge voltage from 0V to 6V. The device features BAT temperature thermistor monitoring with hot/cold profile capabilities and a standalone, RC-settable control interface. It integrates an internal band-gap voltage reference and supports a low-power mode.

Fast charge termination is achieved through monitoring the rate of temperature rise, maximum voltage, maximum temperature, and maximum time. For safety, fast charge is inhibited if battery temperature and voltage are outside configured limits. The BQ2002D is available in an 8-pin DIP or 150-mil SOIC package, suitable for surface mount applications.

This product is currently in the process of being discontinued. New designs should consider alternate products.
