BQ2002PN

Battery Chargers Overview

The BQ2002PN is a CMOS battery charging controller designed for NiCd and NiMH cells. It integrates fast-charge management with termination methods including negative delta voltage (-dV), peak voltage detection (PVD), maximum voltage, temperature limits, and timer cutoff. The device supports trickle and pulse maintenance charging phases. It operates within a supply voltage range of 0 to 70 V and functions across an industrial temperature range of 0°C to 70°C. The component utilizes an 8-pin PDIP package.

Battery Chargers Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm pinout and electrical characteristics. Ensure the procurement channel provides genuine components with traceable manufacturing dates. Confirm that the package type matches the required PCB footprint and thermal constraints for the target application environment.

Battery Chargers Selection Notes

Select this component for applications requiring cost-effective charge management for single-cell NiCd or NiMH batteries. Consider its standalone capability which minimizes external component count. Evaluate if the specified operating temperature range meets the environmental requirements of the end product before finalizing the design.

Battery Chargers Part Context

This part belongs to the BQ2002 series of battery chargers from Texas Instruments. The series focuses on providing reliable charging termination for nickel-based chemistries. The PN suffix typically denotes the plastic dual in-line package variant, distinguishing it from surface-mount options like the SOIC package found in other series members.

Battery Chargers Replacement Considerations

Consult official substitution guides for compatible alternatives. Verify functional equivalence regarding termination logic and input voltage ranges when considering cross-references.
