LTC6804IG-1#PBF

Overview

The LTC6804IG-1#PBF is a multicell battery stack monitor manufactured by Analog Devices Inc. It operates within a supply voltage range of 11 V to 55 V and features an SSOP-48 package designed for surface mount installation. The device provides a regulated output voltage of 5.6 V with a maximum output current capability of 4 mA. It functions across an industrial temperature range from -40°C to +85°C while consuming a typical operating supply current of 550 uA.

Feature Summary

• Supports monitoring of multiple series-connected cells in high-voltage battery stacks
• Integrates isoSPI isolated serial communication interface for reliable data transmission
• Includes programmable passive cell balancing circuitry to manage cell voltage disparities

Applications

• Electric vehicle battery management systems
• Hybrid electric vehicle powertrain monitoring
• Grid-scale energy storage system supervision
• Uninterruptible power supply (UPS) battery arrays

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix #PBF indicates tube packaging and lead-free compliance. Check current availability status as supply may be restricted or subject to factory special orders. Ensure environmental compliance documentation matches project requirements before finalizing procurement decisions.

Selection Notes

Select this variant when a daisy-chain compatible isoSPI interface is required for the LTC6804 family. The IG-1 designation specifies the communication topology suitable for cascading multiple monitors. Consider the SSOP-48 package constraints for PCB layout density. Evaluate thermal performance within the specified operating temperature range for the target application environment.

Part Context

This component belongs to the LTC6804 series of battery monitors, which are engineered for high-precision measurement of series-connected cells. The series supports scalable architectures for monitoring large battery packs. The LTC6804IG-1#PBF specifically utilizes the isoSPI protocol for robust communication in electrically noisy environments common in automotive and industrial settings.

Replacement Considerations

LTC6804IG-2#PBF offers parallel addressing instead of daisy-chain connectivity. LTC6804HG variants provide extended temperature ranges for harsher environments. Verify pin compatibility and software configuration differences when substituting these alternatives.
