MAX17841BGUE/V+T

Overview

The MAX17841BGUE/V+T is a high-performance, automotive-grade SPI communication interface designed for battery monitoring systems. It supports up to four daisy-chained devices and features a 20MHz serial clock rate with 16-bit data resolution. The device integrates an internal voltage reference and operates within a supply voltage range of 2.7V to 5.5V. It includes programmable fault detection capabilities such as overvoltage, undervoltage, and open-wire sensing. The component is qualified to AEC-Q100 standards and functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Supports daisy-chain topology for connecting multiple units via a standard SPI-compatible interface
• Integrates internal voltage reference to minimize external component count
• Provides comprehensive fault detection including overvoltage, undervoltage, and open-wire conditions

Applications

• Automotive battery management systems (BMS)
• Electric vehicle (EV) and hybrid electric vehicle (HEV) battery packs
• Industrial battery monitoring applications

Procurement Notes

Verify the specific suffix 'V' indicates automotive qualification compliance against official Analog Devices documentation. Confirm package integrity upon receipt, as the device utilizes a small outline package. Ensure static-safe handling procedures are followed during installation due to the sensitivity of the integrated circuit inputs.

Selection Notes

Select this component when designing systems requiring robust fault detection and daisy-chain connectivity for battery cells. It is suitable for environments demanding high reliability and wide operating temperature ranges. Consider the pinout compatibility if replacing legacy Maxim Integrated parts in existing automotive designs.

Part Context

This part belongs to the MAX178xx family of battery monitor interfaces developed by Maxim Integrated, now part of Analog Devices. These components are engineered specifically for automotive applications, offering precise voltage measurement and diagnostic features essential for modern electric and hybrid vehicle powertrain architectures.

Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives. Cross-reference with other members of the MAX178xx series for functional compatibility.
