BQ2002TSN Description

Short technical summary and product information.

The BQ2002TSN from Texas Instruments is a low-cost CMOS battery charge controller IC designed for reliable charge termination for NiCd and NiMH battery applications. It can control a current-limited or constant-current supply, making it suitable for stand-alone or system-integrated chargers.

 

This IC integrates fast charge with optional top-off and pulsed-trickle control for charging one or more NiCd or NiMH battery cells. Fast charge is initiated upon application of the charging supply or battery replacement. For safety, fast charge is inhibited if battery temperature and voltage are outside configured limits. Termination methods include rate of temperature rise, maximum voltage, maximum temperature, and maximum time.

 

Key electrical specifications include a maximum charge current of 2A, an input voltage range of 4V to 6V (absolute max 7V), and a battery charge voltage range of 0V to 6V. The operating temperature range is 0°C to 70°C.

 

The BQ2002TSN is available in an 8-SOIC surface mount package. It features BAT temperature thermistor monitoring and direct LED output for charge status indication. The control interface is standalone and RC-settable.
