LTC6804HG-1#TRPBF

Overview

The LTC6804HG-1#TRPBF is a high-voltage, multi-cell 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. The device features an addressable isoSPI interface for daisy-chaining multiple monitors. It is housed in a 48-SSOP package and functions as a precision battery management IC designed for automotive applications.

Feature Summary

• Monitors up to twelve series-connected battery cells with high precision
• Utilizes addressable isoSPI interface for robust communication
• Designed for high-voltage battery stack monitoring applications

Applications

• Automotive battery management systems
• High-voltage electric vehicle battery stacks
• Industrial energy storage monitoring

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm RoHS compliance status through official documentation. Ensure the component matches the exact Analog Devices part number to avoid compatibility issues with development tools like DC1894B.

Selection Notes

Select this component for applications requiring monitoring of up to twelve series cells. Consider the 48-SSOP package size for layout constraints. Verify that the system voltage remains within the 11 V to 55 V operating range. Evaluate the need for addressable isoSPI communication if multiple units are cascaded.

Part Context

This part belongs to the LTC6804 family of battery monitors from Analog Devices. It is specifically the HG-1 variant optimized for high-grade automotive environments. Related development tools include the DC1894B demonstration board for evaluation purposes.

Replacement Considerations

LTC6804IG-1#TRPBF offers similar functionality with potentially different temperature or grade specifications. LTC6804HG-2#TRPBF provides monitoring for up to fourteen cells instead of twelve.
