BQ78PL114RGZR

Battery Management Overview

The BQ78PL114RGZR is a PowerLAN Master Gateway Battery Management Controller featuring PowerPump cell balancing technology. It supports lithium-ion battery packs with 3 to 16 cells and operates within a temperature range of -40°C to +85°C. The device utilizes an SMBus interface for communication and is housed in a 48-VQFN package. Designed for high-voltage applications, it integrates protection mechanisms against overcurrent, overtemperature, over/under voltage, and short circuits.

Battery Management Feature Summary

• Integrates PowerPump cell balancing technology for active charge redistribution
• Functions as a master gateway controller within the PowerLAN architecture
• Supports multi-cell lithium-ion battery configurations up to sixteen cells

Battery Management Applications

• High-voltage electric vehicle traction battery systems
• Industrial energy storage system management
• Power tool battery pack monitoring

Battery Management Procurement Notes

Verify the specific suffix 'RGZR' corresponds to the tape-and-reel packaging variant rather than the 'RGZT' reel configuration. Confirm that the component meets RoHS compliance standards required for your assembly process. Ensure the ordering quantity aligns with the manufacturer's standard factory pack multiples to avoid cut-tape premiums or availability issues.

Battery Management Selection Notes

Select this component when designing systems requiring a centralized master controller for complex battery architectures. It is suitable for applications demanding integrated active cell balancing without external discrete drivers. Consider the 48-VQFN footprint constraints during PCB layout planning to ensure adequate thermal dissipation and signal integrity for the SMBus interface connections.

Battery Management Part Context

This part belongs to Texas Instruments' PowerLAN family, designed for scalable battery management solutions. It complements slave monitors like the BQ76PL102 series to form complete battery stacks. The device provides a centralized approach to managing high-voltage lithium-ion packs, distinguishing itself from single-cell gas gauges by offering comprehensive pack-level control and balancing capabilities.

Battery Management Replacement Considerations

The BQ78PL116RGZT serves as a related model within the same family. Verify functional equivalence regarding cell count support and interface compatibility before substitution.
