LTC6806ILW#3ZZPBF

Overview

The LTC6806ILW#3ZZPBF is a multi-cell battery stack monitor manufactured by Analog Devices Inc. It operates within a supply voltage range of 4.75 V to 150 V and provides a regulated 5 V output. The device supports up to twelve series-connected cells with an input voltage range of 0 V to 100 V per cell. It features AEC-Q100 qualification for automotive applications and utilizes isoSPI communication interface. The component is housed in a 28-lead Wide SOIC package designed for surface mount installation.

Feature Summary

• Monitors up to twelve series-connected battery cells simultaneously
• Supports high-voltage operation with individual cell inputs up to 100 V
• Integrates isoSPI interface for secure, noise-immune communication
• Qualified for automotive environments under AEC-Q100 standards

Applications

• Multi-fuel cell monitoring systems
• High-voltage battery management in electric vehicles
• Industrial energy storage systems
• Uninterruptible power supply (UPS) stacks

Procurement Notes

Verify the specific suffix #3ZZPBF against official Analog Devices documentation to confirm packaging and tape-and-reel specifications. Confirm current availability status as distribution channels may list limited stock or special order requirements. Ensure the procurement source provides valid RoHS compliance data and traceability certificates required for automotive-grade components.

Selection Notes

Select this component when monitoring twelve or fewer series cells requiring high common-mode voltage tolerance. The isoSPI interface is suitable for noisy industrial or automotive environments where galvanic isolation is managed externally. Compare against the standard LTC6806 if extended temperature ranges or different package options are not required for the specific application design.

Part Context

This part belongs to the LTC680x family of battery monitors from Analog Devices. It is specifically designed for applications requiring precise voltage measurement across multiple series-connected cells in high-voltage stacks. The device integrates precision analog front-end circuitry with digital control logic to facilitate accurate state-of-charge and state-of-health calculations.

Replacement Considerations

Direct substitutes include other members of the LTC680x family such as the LTC6804 or LTC6805, depending on the required number of monitored cells. Verify pin compatibility and software register mapping before substitution. Alternative devices must support similar input voltage ranges and isoSPI communication protocols.
