The BQ2002SNTR from Texas Instruments is a low-cost CMOS battery charge controller IC designed for reliable charging of NiCd and NiMH battery applications. It features a linear control topology and is suitable for charging 1 to 4 series cells.
Key electrical specifications include a maximum charge current of 2A, an input voltage range of 4V to 7V, and battery charge voltages from 0V to 6V. The device incorporates battery temperature monitoring via a thermistor for hot/cold profile management. It offers standalone, RC-settable control and supports multi-chemistry battery types.
Packaged in an 8-SOIC surface mount package, the BQ2002SNTR is designed for efficient battery charging. It provides direct LED output for charge status indication and supports fast-charge termination by various methods including negative delta voltage (-V), maximum voltage, maximum temperature, and maximum time. The product is noted as being in the process of discontinuation, with new designs advised to consider alternate products.
This IC is ideal for cost-effective, stand-alone or system-integrated chargers where precise control over NiCd and NiMH battery charging is required. Its features include optional top-off charge and selectable pulse trickle charge rates.
