The BQ2002SN from Texas Instruments is a low-cost CMOS battery charge controller IC designed for reliable charging termination of NiCd and NiMH battery applications. It supports multi-chemistry batteries and operates with a 6V supply voltage.
This IC integrates fast-charge capabilities with optional top-off and pulsed-trickle control. Fast charge termination can be achieved through various methods including negative delta voltage (-dV), peak voltage detection (PVD), maximum voltage, maximum temperature, and maximum time. The device features direct LED output for charge status indication and an internal band-gap voltage reference.
Packaged in an 8-SOIC (0.154", 3.90mm Width) surface mount package, the BQ2002SN is suitable for cost-effective stand-alone or system-integrated chargers. It operates within a temperature range of 0°C to 70°C.
For safety, fast charge is inhibited if battery temperature and voltage are outside configured limits. The device offers selectable pulse trickle charge rates and a low-power mode.
