LTC6811HG-2#3ZZPBF

Overview

The LTC6811HG-2#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 an output voltage of 5.7 V. The device is housed in an SSOP-48 package designed for surface mount installation. It functions as a battery protection component suitable for multiple cell types, with a specified operating temperature range from -40 C to +125 C and a quiescent current of 550 uA.

Feature Summary

• Monitors up to twelve individual cells within a high-voltage battery stack
• Supports operation across extended industrial temperature ranges

Applications

• Multicell battery stack monitoring
• Battery protection systems

Procurement Notes

Verify availability status carefully, as this specific part number may be subject to limited supply or factory special order conditions. Confirm the exact suffix matches required specifications before ordering. Check official distributor channels for current stock levels and lead times. Ensure compatibility with existing system voltage requirements.

Selection Notes

Select this component when monitoring twelve cells in series is required. Ensure the system voltage remains between 11 V and 55 V. Verify that the SSOP-48 package fits the PCB layout constraints. Consider the extended temperature rating if operating in harsh environments.

Part Context

This part belongs to the LTC6811 series of battery monitors. It shares functional similarities with other variants like the IG grade, which differs primarily in temperature rating. Related parts include the LTC6810 for six-channel applications and the LTC6813 for daisy-chain interfaces.

Replacement Considerations

LTC6811IG-2#3ZZPBF offers identical electrical performance but with a reduced maximum operating temperature of +85 C compared to the HG grade's +125 C. Verify thermal requirements before substitution.
