LTC6804HG-2#TRPBF

Overview

The LTC6804HG-2#TRPBF is a high-voltage multicell battery stack monitor manufactured by Analog Devices Inc. It operates within a supply voltage range of 11 V to 55 V and supports up to twelve series-connected cells with a maximum cell voltage of 5.6 V per channel. The device utilizes an addressable isoSPI interface for communication, enabling daisy-chaining of multiple monitors in high-voltage environments. Packaged in a 48-pin SSOP, it is designed for automotive applications requiring robust monitoring capabilities.

Feature Summary

• Supports monitoring of up to twelve series-connected battery cells
• Features addressable isoSPI interface for secure daisy-chain communication
• Designed for high-voltage battery stack management applications

Applications

• Automotive battery management systems
• High-voltage electric vehicle traction batteries
• Industrial energy storage systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix #TRPBF indicates tape-and-reel packaging. Check current lifecycle status as availability may be restricted. Ensure compliance with RoHS directives and relevant automotive quality standards before integration into production designs.

Selection Notes

Select this component when monitoring twelve series cells is required. Compare against the LTC6804IG variant if industrial temperature ranges suffice instead of automotive specifications. Evaluate the LTC6803 if fewer than twelve cells need monitoring. Consider the LTC6806 for higher cell counts exceeding twelve.

Part Context

This part belongs to the LTC6804 family of battery monitors from Analog Devices. It shares core architecture with variants like the LTC6804HG-1#TRPBF but differs in internal configuration options. The HG suffix typically denotes automotive-grade qualification. It complements other power management ICs in complete battery management solutions.
