Procurement Notes

Verify the specific suffix and packaging configuration against official Analog Devices documentation before ordering. Confirm that the DFN-14 footprint matches your PCB layout requirements. Ensure compatibility with your system's communication interface and authentication keys. Check current availability status as distribution may vary by region.

Selection Notes

Select this component when a single-cell solution with integrated protection and high accuracy is required. The ModelGauge m5 technology offers superior performance compared to basic voltage-based gauges. Consider the thermal operating range and package size constraints during design. Verify that the host system supports the necessary 1-Wire or I2C interface protocols for data retrieval.

Part Context

This part belongs to the Maxim Integrated battery management portfolio, now under Analog Devices. It represents a compact solution for applications where board space is limited but accuracy is critical. The integration of protection and fuel gauging reduces the overall component count in the power management subsystem.

Replacement Considerations

Consult official substitution lists for compatible alternatives. Verify pinout compatibility and algorithm differences if replacing with other ModelGauge variants. Ensure any substitute maintains the required authentication capabilities and protection thresholds.
