MAX17851AUP/V+T

Overview

The MAX17851AUP/V+T is an automotive-grade SPI to UART bridge monitor manufactured by Analog Devices Inc./Maxim Integrated. It converts SPI communication formats into battery management UART protocols for high-voltage battery systems. The device operates within a supply voltage range of 2.375V to 5.5V and consumes 920µA of operating supply current. It supports a single channel and functions across an operating temperature range of -40°C to 125°C. The component holds AEC-Q100 qualification and is designed for surface mount applications.

Feature Summary

• Converts SPI communication formats to battery management UART protocols
• Automotive-grade design with AEC-Q100 qualification
• Single-channel bridge monitor architecture

Applications

• High-voltage battery management systems in electric vehicles
• Battery monitoring in energy storage systems
• Large lithium-ion pack management units

Procurement Notes

Verify the specific suffix (e.g., +T) against official documentation to ensure correct packaging and reel specifications. Confirm that the AEC-Q100 qualification aligns with target automotive requirements. Check regional availability restrictions as distribution may vary. Ensure the supply voltage range matches the system power architecture before integration.

Selection Notes

Select this component when a dedicated bridge between SPI interfaces and battery management UART protocols is required. It is suitable for applications demanding automotive reliability and wide temperature operation. Consider the single-channel limitation if multiple independent bridges are needed. Verify compatibility with existing battery management controller architectures.
