BQ296113DSGT

Battery Management Overview

The BQ296113DSGT is a battery management integrated circuit designed for overvoltage protection in lithium-ion battery packs consisting of two to four series-connected cells. It features an integrated Low Dropout (LDO) regulator providing selectable output voltages of 1.8 V, 2.5 V, or 3.3 V with a maximum output current of 1 mA. The device operates within a supply voltage range up to 20 V and draws a typical quiescent current of 1 µA. It is housed in an 8-pin WSON package and supports surface-mount installation. The component functions reliably across an operating temperature range from -40 °C to +110 °C.

Battery Management Feature Summary

• Provides dedicated overvoltage protection for 2S to 4S lithium-ion battery configurations
• Integrates an LDO regulator with selectable output voltage options
• Designed for ultra-low power consumption suitable for portable applications

Battery Management Applications

• Protection circuits for multi-cell lithium-ion battery packs
• Portable electronic devices requiring cell monitoring
• Battery management systems in consumer electronics

Battery Management Procurement Notes

Verify the specific suffix designation against official Texas Instruments documentation to confirm pinout configuration and functional variants. Ensure the procurement source provides valid RoHS compliance data and original manufacturer traceability. Cross-reference the part number with authorized distributor catalogs to validate authenticity and avoid counterfeit components. Confirm that the packaging format matches production requirements.

Battery Management Selection Notes

Select this component when designing protection schemes for 2S to 4S lithium-ion architectures requiring integrated voltage regulation. Evaluate the need for the specific LDO output voltage setting relative to downstream load requirements. Consider the low quiescent current specification for battery life optimization. Verify that the WSON-8 package dimensions fit the available PCB real estate constraints.

Battery Management Part Context

This part belongs to the BQ2961 series of battery protection ICs from Texas Instruments. It complements other models like the BQ296107 by offering additional integrated regulation capabilities. The series targets compact battery pack designs where space efficiency and low standby current are critical performance factors for modern portable energy storage solutions.

Battery Management Replacement Considerations

The BQ296107DSGT serves as a related variant within the same family but lacks the integrated LDO output feature. Substitution requires verifying if the application necessitates the regulated output or if external regulation is acceptable. Ensure compatibility with existing board layout and control logic before replacing.
