BQ771612DPJR

Battery Management Overview

The BQ771612DPJR is a battery protection integrated circuit designed for lithium-ion battery packs consisting of two to four series-connected cells. Manufactured by Texas Instruments, this component operates within an ambient temperature range of -40°C to 110°C and utilizes an 8-WSON (3x4) surface-mount package with an exposed pad. It provides overvoltage fault protection to ensure cell safety during charging or abnormal conditions.

Battery Management Feature Summary

• Provides overvoltage protection for multi-cell lithium-ion battery configurations
• Operates across extended industrial temperature ranges suitable for harsh environments

Battery Management Applications

• Protection circuits for portable electronic devices using 2-4 cell lithium-ion batteries
• Battery management systems in consumer electronics requiring compact form factors
• Industrial equipment utilizing multi-cell lithium-ion power sources

Battery Management Procurement Notes

Verify the specific suffix DPJR against official Texas Instruments documentation to confirm the 8-WSON package type and tape-and-reel packaging configuration. Ensure compatibility with RoHS3 standards and check for any recent Product Change Notifications regarding material or assembly modifications before finalizing procurement orders.

Battery Management Selection Notes

Select this component when designing protection circuits for 2 to 4 series lithium-ion cells requiring overvoltage monitoring. The choice depends on the need for a compact 8-WSON footprint and operation up to 110°C. Verify that the internal delay timer characteristics align with the specific application's transient immunity requirements.
