MAX4210BETT

Current Regulation/Management Overview

The MAX4210BETT is a high-side power and current monitor manufactured by Analog Devices Inc./Maxim Integrated. It provides an analog output voltage proportional to the load power by multiplying load current and source voltage. The device operates with an input source voltage range of +4V to +28V and a power-supply voltage range of +2.7V to +5.5V. It features ±1.5% maximum current-sense accuracy and ±1.5% maximum power-sense accuracy. The unit includes three current/power gain options and utilizes a small 6-pin TDFN package.

Current Regulation/Management Feature Summary

• Provides real-time monitoring of current and power via an analog output proportional to load consumption
• Measures load current using a high-side current-sense amplifier that does not interfere with the ground path
• Integrates two uncommitted comparators for system protection logic

Current Regulation/Management Applications

• Overpower circuit breakers
• Smart battery packs and chargers
• Short-circuit protection circuits
• Power-supply displays and measurement instrumentation

Current Regulation/Management Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm specific suffix designations against official datasheets to ensure correct package type and temperature rating. Request original documentation to validate manufacturing origin and revision history prior to integration into production designs.

Current Regulation/Management Selection Notes

Select this component when high-side sensing is required to preserve the load ground reference in battery-powered systems. Evaluate the ±1.5% accuracy specifications against system tolerance requirements. Consider the 380µA supply current for low-power applications. Ensure the +4V to +28V input range matches the source voltage profile of the target application.

Current Regulation/Management Part Context

The MAX4210 belongs to the MAX4210/MAX4211 family of low-cost, low-power monitors. It is designed for applications requiring precise power management without ground path interference. The device distinguishes itself through its ability to multiply load current and source voltage directly on-chip, providing a comprehensive power monitoring solution in a compact footprint.

Current Regulation/Management Replacement Considerations

Consult official substitution lists for verified alternatives. Generic replacements may lack specific accuracy or package compatibility.
