LTC6804IG-2#PBF

Overview

The LTC6804IG-2#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 output voltage of 5.6 V with an output current capability of 4 mA. The device consumes a typical operating supply current of 550 uA. It is housed in a 48-pin SSOP package designed for surface mount installation. The component supports an extended industrial temperature range from -40 C to +85 C and is classified under Battery Management products.

Feature Summary

• Monitors multiple series-connected battery cells in high-voltage stacks
• Utilizes addressable isoSPI interface for daisy-chain communication
• Supports multiple battery chemistries for versatile application

Applications

• Electric vehicle battery management systems
• Energy storage system cell monitoring
• Industrial battery pack supervision

Procurement Notes

Verify the specific suffix #PBF indicates tube packaging when sourcing. Confirm the IG-2 grade matches required automotive or industrial specifications. Check RoHS compliance status via official documentation. Ensure availability aligns with restricted supply conditions noted by distributors. Validate pinout compatibility with existing PCB layouts before procurement.

Selection Notes

Select this component for applications requiring precise monitoring of large battery stacks. The isoSPI interface reduces wiring complexity compared to parallel architectures. Consider the 48-pin SSOP package constraints for board space. Evaluate the 550 uA quiescent current against system power budgets. Verify that the 11 V minimum supply voltage suits the system's operational range.

Part Context

This part belongs to the LTC6804 family of battery monitors. It is distinct from variants like the LTC6803 which support different cell counts. Development tools such as DC1894B are available for evaluation. The component integrates analog front-end circuitry specifically optimized for high-voltage battery stacks.
