LTC6803IG-3#3ZZPBF

Overview

The LTC6803IG-3#3ZZPBF is a battery stack monitor from Analog Devices, designed for multicell lithium-ion battery management. It operates within a supply voltage range of 4 V to 55 V and features an SSOP-44 surface-mount package. The device provides a regulated 5 V output with an 8 mA current capability. It functions across an industrial temperature range of -40°C to +85°C, drawing a typical operating supply current of 780 uA. This component is categorized under Battery Protection within the PMIC family.

Feature Summary

• Monitors multiple cells in a high-voltage battery stack configuration
• Provides regulated auxiliary power output for system support
• Supports standard serial communication interfaces for data retrieval

Applications

• Lithium-ion battery stack monitoring
• Multicell battery protection systems
• Industrial battery management applications

Procurement Notes

Verify availability status carefully as this part number is currently listed as having restricted supply or limited distribution through major distributors like Mouser. Confirm lead times and allocation constraints directly with authorized suppliers before finalizing procurement plans, as stock levels may be unstable.

Selection Notes

Select this variant when a 12-channel multicell monitor is required with an extended industrial temperature rating up to 85°C. Ensure the application voltage does not exceed the 55 V maximum limit. Compare against the HG series if higher thermal tolerance above 85°C is needed, or verify that the SSOP-44 package fits the PCB layout constraints.

Part Context

This component belongs to the LTC6803 series of battery monitors. It shares functional similarities with other variants such as the LTC6803IG-2#3ZZPBF and LTC6803HG-3#3ZZPBF, differing primarily in temperature ratings and specific suffix designations. It serves as a core sensing element in complex battery management architectures requiring precise cell voltage tracking.
