LTC6803IG-1#3ZZPBF

Overview

The LTC6803IG-1#3ZZPBF is a multicell battery stack monitor manufactured by Analog Devices Inc., designed for lithium-ion battery management applications. It operates within a supply voltage range of 4 V to 55 V and features an integrated 5 V output capable of delivering 8 mA. The device is housed in a 44-pin SSOP package with surface-mount installation. It supports a wide operating temperature range from -40°C to +85°C and maintains a low quiescent current of 780 µA during operation.

Feature Summary

• Monitors multiple cells in high-voltage battery stacks
• Integrates passive cell balancing capabilities
• Supports daisy-chain communication for system expansion

Applications

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

Procurement Notes

Verify the specific suffix #3ZZPBF against official Analog Devices documentation to confirm pinout, temperature grade, and packaging specifications. Ensure compatibility with existing board layouts and thermal requirements before procurement. Confirm availability status through authorized distributors as supply may be restricted.

Selection Notes

Select this component for applications requiring precise monitoring of series-connected lithium-ion cells within a 4 V to 55 V input range. Consider the industrial temperature rating of +85°C maximum when designing for harsh environments. Verify that the SSOP-44 package fits the available PCB footprint and that the 780 µA quiescent current meets system power constraints.

Part Context

This part belongs to the LTC6803 family of battery monitors, which are optimized for high-voltage battery stacks. The IG-1 variant specifically denotes the industrial temperature range and standard packaging configuration. It serves as a core component in battery management systems requiring accurate cell voltage measurement and balancing.

Replacement Considerations

Check for direct substitutes within the LTC6803 family such as the HG-1 variant for extended temperature ranges. Verify pin-to-pin compatibility and electrical parameter alignment before substitution.
