MAX4211DETE

Current Regulation/Management Overview

The MAX4211DETE is a high-side power and current monitor manufactured by Analog Devices Inc. (formerly Maxim Integrated). It integrates a precision current-sense amplifier with an analog multiplier to measure load power directly. The device operates within an input voltage range of 4V to 28V and supports a supply voltage from 2.7V to 5.5V. It features ±0.5% accuracy for current monitoring and is housed in a 16-TQFN (4x4) surface-mount package. The operational temperature range extends from -40°C to +85°C, making it suitable for industrial applications requiring precise DC error budgeting.

Current Regulation/Management Feature Summary

• Integrates a high-side current-sense amplifier with an analog voltage multiplier for direct power measurement
• Provides a proportional output voltage representing the product of load voltage and current
• Supports ratioed measurements to minimize dependency on ADC reference voltage accuracy

Current Regulation/Management Applications

• Battery charging and discharging current monitoring
• High-reliability systems requiring advanced current sensing
• Power management circuits utilizing analog multipliers for constant-power sources

Current Regulation/Management Procurement Notes

Verify the specific suffix 'DETE' against the manufacturer's official part numbering system to confirm package type and temperature grade. Confirm availability status as some variants may be discontinued or restricted. Ensure compatibility with existing PCB footprints for the 16-TQFN package. Cross-reference with Analog Devices documentation for any recent product change notices or lifecycle updates affecting this specific marking code.

Current Regulation/Management Selection Notes

Select this component when simultaneous measurement of high-side current and total load power is required without external digital processing. The integrated multiplier simplifies design compared to discrete solutions. Consider the 4V to 28V input range for bus voltages. Evaluate the ±0.5% accuracy against system requirements. Ensure the 16-TQFN package fits the mechanical constraints. Verify thermal performance within the -40°C to +85°C operating range for the target environment.

Current Regulation/Management Part Context

The MAX4211 belongs to the MAX4210/MAX4211 family of high-side power monitors. While the MAX4210 focuses primarily on current sensing, the MAX4211 adds the analog multiplication capability for power monitoring. This family is designed for applications needing accurate DC error budgeting and simplified signal paths for battery-powered or industrial systems. The DE suffix typically denotes a specific temperature grade and packaging configuration within the Maxim/Analog Devices lineup.

Current Regulation/Management Replacement Considerations

Public confirmed substitutes include other members of the MAX4210/MAX4211 family such as the MAX4211CETE+T or MAX4211EEVKIT evaluation boards for testing. Direct pin-compatible replacements should be verified via Analog Devices cross-reference tools. No generic industry alternatives are confirmed; only official Analog Devices parts are listed.
