LTC6803IG-4#3ZZTRPBF

Overview

The LTC6803IG-4#3ZZTRPBF is a multicell battery stack monitor from Analog Devices, housed in an SSOP-44 surface-mount package. It operates within a supply voltage range of 4 V to 55 V and draws a typical operating current of 780 uA. The device provides a regulated 5 V output capable of sourcing 8 mA. Designed for lithium-ion battery applications, it supports monitoring stacks with a maximum operating temperature of +85°C and a minimum of -40°C.

Feature Summary

• Monitors multiple cells in series-connected battery stacks
• Provides internal regulation for peripheral power
• Supports serial communication for data readout

Applications

• Lithium-ion battery stack monitoring
• Battery protection systems
• Electric vehicle battery management

Procurement Notes

Verify the specific suffix #3ZZTRPBF against official Analog Devices documentation to confirm reel packaging and tape-and-reel specifications. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as regulatory details may vary by production batch. Ensure the SSOP-44 package dimensions match your PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when monitoring high-voltage series battery strings requiring precise cell voltage measurement. The SSOP-44 package offers a compact solution for space-constrained designs. Consider the thermal performance limits of the +85°C rating for your specific enclosure environment. Verify that the 780 uA quiescent current aligns with your system's power budget constraints.

Part Context

This part belongs to the LTC6803 family of battery monitors, designed for high-accuracy cell voltage measurement. The IG-4 variant specifies the industrial temperature grade and SSOP-44 package. The #3ZZ suffix typically denotes specific packaging configurations such as tape and reel, distinguishing it from tube-packaged equivalents like the #PBF variants.
