LTC6803HG-2#PBF

Battery Management Overview

The LTC6803HG-2#PBF is a multicell battery stack monitor manufactured by Analog Devices Inc. It operates within a supply voltage range of 4 V to 55 V and features an integrated 5 V regulator delivering up to 8 mA output current. The device supports monitoring of multiple series-connected lithium-ion cells and functions across an extended industrial temperature range from -40°C to +125°C. It is housed in a 44-pin SSOP package designed for surface mount installation, with a quiescent operating current of 780 uA.

Battery Management Feature Summary

• Enables precise monitoring of multicell battery stacks through dedicated cell voltage measurement channels.
• Integrates internal regulators and low-power operation suitable for high-voltage battery management systems.
• Provides robust thermal performance capabilities for demanding industrial and automotive environments.

Battery Management Applications

• Lithium-ion battery stack monitoring
• Multicell battery management systems
• Industrial power management ICs

Battery Management Procurement Notes

Verify component authenticity and datasheet revisions directly with Analog Devices or authorized distributors. Confirm that the specific suffix matches the required temperature grade and package variant. Check for any product change notifications affecting pinout or electrical characteristics before finalizing procurement specifications.

Battery Management Selection Notes

Select this variant when extended high-temperature operation up to 125°C is required compared to standard commercial grades. Ensure the system design accommodates the 44-pin SSOP footprint and validates compatibility with the 4V to 55V input range. Compare against other family members like the IG version if lower power consumption is prioritized over extreme temperature tolerance.

Battery Management Part Context

This component belongs to the LTC6803 series of battery monitors from Analog Devices. It shares the core architecture with variants such as the LTC6803IG-2#PBF but differs in operational temperature specifications and potentially internal calibration parameters. The HG suffix typically denotes the high-temperature grade within this product line.

Battery Management Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify cross-compatibility with other LTC6803 variants based on specific temperature and current requirements.
