BQ78PL116RGZR

Battery Management Overview

The BQ78PL116RGZR is a PowerLAN Master Gateway Battery Management Controller designed for lithium-ion battery packs. It supports configurations of 3 to 16 series cells and operates within a temperature range of -40°C to +85°C. The device utilizes a 48-VFQFN (7x7) package with exposed pad for surface mount installation. Communication is facilitated via an SMBus interface, enabling integration into complex battery management systems.

Battery Management Feature Summary

• Integrates PowerPump cell balancing technology for active charge redistribution
• Functions as a master gateway controller within the PowerLAN architecture
• Provides comprehensive fault protection including overcurrent, overtemperature, and short circuit detection

Battery Management Applications

• Lithium-ion battery pack management in industrial equipment
• Master controller nodes in modular battery storage systems
• Electric vehicle traction battery monitoring applications

Battery Management Procurement Notes

Verify the specific suffix against the manufacturer datasheet to confirm package type and tape/reel specifications. Ensure compatibility with the host system's SMBbus voltage levels and logic thresholds. Confirm that the operating temperature range meets the environmental requirements of the intended deployment scenario before finalizing procurement.

Battery Management Selection Notes

Select this component when a centralized master controller is required for multi-cell lithium-ion architectures. It is suitable for designs necessitating active cell balancing through integrated PowerPump technology. Consider the 48-pin QFN footprint constraints and thermal dissipation capabilities during the PCB layout phase to ensure reliable operation under maximum load conditions.

Battery Management Part Context

This part belongs to Texas Instruments' PowerLAN family, which facilitates communication between multiple battery management devices. It serves as a high-level controller coordinating data from slave gauges or direct cell sensing. The RGZR suffix typically denotes a tape and reel packaging format optimized for automated surface-mount assembly processes.

Battery Management Replacement Considerations

The BQ78PL114 is a documented variant within the same family offering similar gateway functionality. Verify pinout compatibility and software register mapping before substitution. Ensure that any alternative component supports the required number of series cells and maintains SMBus interoperability with existing system slaves.
