Battery Management datasheet and documents for BQ29405DCT3

BQ29405DCT3

Battery Management Overview

The BQ29405DCT3 is a voltage protection integrated circuit designed for second-level battery management in lithium-ion systems. It supports configurations with two, three, or four cells and operates within an ambient temperature range of -25°C to 85°C. The device utilizes an 8-pin Small Outline package (SM8) variant. A fixed detection threshold voltage of 4.65V is specified for overvoltage monitoring functions.

Battery Management Feature Summary

Provides secondary voltage protection for multi-cell lithium-ion battery packs
Integrates fixed overvoltage detection logic without adjustable thresholds
Operates across extended industrial temperature ranges

Battery Management Applications

Secondary protection circuits for portable electronic devices
Voltage monitoring in consumer power tool battery packs
Backup power system cell balancing and safety management

Battery Management Procurement Notes

Verify the specific suffix designation against official Texas Instruments documentation to confirm exact packaging and environmental compliance status. Ensure the procurement channel provides valid traceability for automotive or industrial grade requirements. Confirm RoHS and lead-free certification details match project specifications before finalizing orders.

Battery Management Selection Notes

Select this component when a fixed 4.65V overvoltage threshold is required for secondary battery protection. It is suitable for designs needing compact surface-mount integration in 8-pin packages. Consider alternative models if adjustable thresholds or different cell counts are necessary for the specific application architecture.

Battery Management Part Context

This part belongs to the BQ2940x family of battery management ICs from Texas Instruments. These components focus on enhancing safety by providing redundant protection layers beyond primary control mechanisms. The series addresses critical needs in preventing overcharge conditions in portable energy storage applications.
