LTC6803HG-4#PBF

Overview

The LTC6803HG-4#PBF is a multicell battery stack monitor manufactured by Analog Devices Inc., designed for charge management applications. It operates within a supply voltage range of 4 V to 55 V and provides a regulated output voltage of 5 V with an output current capability of 4 mA. The device supports monitoring of multiple cell batteries, specifically lithium-ion types, and functions reliably across an extended temperature range from -40°C to +125°C. It consumes a typical operating supply current of 12 µA. The component is housed in a 44-pin SSOP package and is suitable for surface mount installation.

Feature Summary

• Monitors multiple cells in a battery stack configuration
• Supports passive balancing through selective resistive loading
• Enables daisy-chaining of up to ten devices via board-to-board ribbon cable interconnects

Applications

• Lithium-ion battery stack monitoring systems
• Evaluation circuit demonstrations for functional operation verification
• Battery management systems requiring passive cell balancing

Procurement Notes

Verify availability status as the part may be subject to limited supply or factory special order conditions. Confirm RoHS compliance details and ensure compatibility with the specified SSOP-44 footprint during procurement planning. Check for any regional sales restrictions that may affect acquisition channels.

Selection Notes

Select this component for applications requiring high-voltage battery stack monitoring with low quiescent current consumption. Ensure the design accommodates the 4 V to 55 V operating range and utilizes the SSOP-44 package constraints. Consider the need for external resistive loads for passive balancing functionality when integrating into the system architecture.
