BQ2002CSNTR

Battery Chargers Overview

The BQ2002CSNTR is a CMOS battery charging controller manufactured by Texas Instruments, designed for NiCd and NiMH battery applications. It integrates fast-charge management with configurable termination methods including negative delta voltage (-dV), peak voltage detection (PVD), maximum voltage, maximum temperature, and maximum time limits. The device supports standalone operation or system integration, offering optional top-off and pulsed trickle charge control. It operates within a supply voltage range of 4.5V to 5.5V and functions across an ambient temperature range of 0°C to 70°C. Packaged in an 8-SOIC surface-mount format, it provides reliable charging termination for single-cell configurations.

Battery Chargers Procurement Notes

Verify the specific suffix 'C' against official documentation to confirm temperature rating and package variant. Confirm RoHS compliance status as per current datasheet revisions. Check for product change notifications regarding manufacturing location or material updates. Ensure ordering quantities align with tape and reel specifications provided in the manufacturer's packaging data.

Battery Chargers Selection Notes

Select this component for applications requiring precise termination of NiCd/NiMH cells using -dV or PVD methods. Consider its standalone capability if external microcontroller logic is unavailable. Evaluate the need for low standby power modes in portable devices. Compare performance against similar family members like the BQ2002F if specific timing constraints differ.

Battery Chargers Part Context
