LTC6811IG-1#3ZZPBF

Overview

The LTC6811IG-1#3ZZPBF is a 12-channel multicell battery stack monitor manufactured by Analog Devices Inc. It operates within a supply voltage range of 11 V to 55 V and provides a regulated output voltage of 5.7 V. The device is housed in an SSOP-48 package designed for surface mount installation. It functions within an industrial temperature range from -40°C to +85°C, with a typical operating supply current of 550 uA.

Feature Summary

• Monitors up to twelve individual cells within a high-voltage battery stack
• Supports daisy-chain communication for cascading multiple devices
• Integrates precision analog front-end circuitry for cell voltage measurement

Applications

• High-voltage battery stack monitoring in electric vehicles
• Energy storage system management
• Industrial battery pack supervision

Procurement Notes

Verify the specific suffix #3ZZPBF against official Analog Devices documentation to confirm package type and environmental compliance. Confirm availability status as distribution channels may indicate restricted supply or limited stock conditions. Ensure the component matches the required industrial temperature grade and pinout configuration for your design.

Selection Notes

Select this part when monitoring twelve cells is required within the specified voltage window. Compare against the LTC6811HG variant if operation above 85°C is necessary. Consider the LTC6810 series if only six channels are sufficient for the application architecture.

Part Context

This component belongs to the LTC6811 family of battery monitors. It shares functional similarities with other members like the IG-2 and HG variants, differing primarily in temperature ratings and internal calibration settings. It serves as a core sensing element in complex battery management architectures requiring high channel counts.
