MAX17852ACB/V+T

Overview

The MAX17852ACB/V+T is a flexible data-acquisition system designed for managing high-voltage and low-voltage battery modules. It features a fully redundant measurement engine capable of measuring 14 cell voltages, one current measurement, and four temperature or system inputs within 263 microseconds. The device operates with a supply voltage range of 3.2 V to 5.5 V and is housed in a 64-LQFP package.

Feature Summary

• Fully redundant measurement engine architecture ensures high reliability during critical battery monitoring operations.
• Simultaneous acquisition of multiple cell voltages, current, and temperature data enables comprehensive state estimation.
• Integrated design supports both high-voltage and low-voltage battery module management applications.

Applications

• High-voltage battery module management
• Low-voltage battery module management
• Battery management systems requiring fast cycle times

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the operating temperature range and package type match your board design requirements. Ensure compatibility with the host microcontroller interface before finalizing procurement decisions.

Selection Notes

Select this component when a complete data-acquisition solution for battery cells is required rather than individual voltage sensors. Consider the 263µs conversion time for systems needing rapid state updates. Evaluate the LQFP-64 footprint against available PCB space constraints.

Part Context

This part belongs to the MAX17852 family of battery management ICs from Analog Devices (formerly Maxim Integrated). It serves as a central node for collecting electrical parameters in series-connected battery stacks, replacing discrete sensor arrays with an integrated multi-channel solution.

Replacement Considerations

Check for direct pin-compatible alternatives within the same product family if supply constraints exist. Verify that any substitute maintains the 263µs measurement speed and 14-cell capacity without requiring schematic changes.

FAQ

What is the maximum number of cell voltages the MAX17852 can measure simultaneously?

The device can measure up to 14 cell voltages simultaneously using its fully redundant measurement engine.

Does the MAX17852 support current and temperature measurements?

Yes, it includes provisions for one current measurement and up to four temperature or system inputs alongside the cell voltage readings.
