BQ296100DSGT

Battery Management Overview

The BQ296100DSGT is a battery protection integrated circuit from Texas Instruments designed for lithium-ion battery packs. It provides overvoltage protection for series-connected cells ranging from two to four in number. The device features an integrated low-dropout regulator (LDO) output capable of delivering up to 14 mA at 7 V, which can power external monitoring or control circuitry. It operates within a supply voltage range of 3 V to 20 V and draws a typical quiescent current of 4 µA. The component is housed in an 8-pin WSON package and supports surface-mount installation. It functions reliably across an extended temperature range from -40 °C to +110 °C.

Battery Management Feature Summary

• Provides dedicated overvoltage protection for multi-cell lithium-ion battery configurations.
• Integrates an LDO output stage to supply stable voltage for auxiliary system components.
• Optimized for ultra-low standby power consumption to preserve battery life during storage.

Battery Management Applications

• Protection circuits for portable electronic devices using 2S to 4S lithium-ion batteries
• Battery management systems requiring independent cell voltage monitoring
• Consumer electronics with strict standby power efficiency requirements

Battery Management Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout and electrical characteristics, as variations exist within the family. Ensure the supplier provides traceable documentation confirming RoHS compliance and authenticity. Cross-reference the ordering part number with the manufacturer's latest release notes to account for any process change notifications that may affect mechanical dimensions or material composition prior to final integration.

Battery Management Selection Notes

Select this component when the application requires simultaneous overvoltage protection and a regulated auxiliary power source for monitoring logic. Compare the 14 mA LDO output capability against the load requirements of the connected microcontroller or sensor array. Evaluate the 4 µA quiescent current against total system sleep current budgets to ensure it meets energy efficiency targets for long-term deployment in portable applications.
