BQ2002 Description

Short technical summary and product information.

The BQ2002 from Texas Instruments is a versatile battery charge controller IC specifically designed for Nickel Cadmium (NiCd) and Nickel-Metal Hydride (NiMH) battery applications. It provides reliable charge termination using methods such as negative delta voltage (-ΔV), maximum voltage, maximum temperature, and maximum time, along with peak voltage detection (PVD).

This IC integrates essential features for cost-effective charger designs, including optional top-off charge capabilities and selectable pulse trickle charge rates. It also supports a low-power mode to reduce system consumption and features a direct LED output to display charge status. The BQ2002 operates with a supply voltage range of 4V to 6V and supports 1 to 4 series cells.

Available in an 8-pin DIP or SOIC package, the BQ2002 is suitable for stand-alone or system-integrated chargers. Its design facilitates the creation of efficient and safe charging solutions for various portable electronic devices.
