MAX4211BETE

Current Regulation/Management Overview

The MAX4211BETE 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's consumed power by multiplying load current and source voltage. The device features a ±0.5% accuracy rating for both current and power sensing. It operates with an input source voltage range of +4V to +28V and a power-supply voltage range of +2.7V to +5.5V. The unit is housed in a 16-TQFN (4x4) surface-mount package.

Current Regulation/Management Feature Summary

• Provides real-time monitoring of current and power consumption via an analog output signal
• Utilizes high-side current-sense amplification to avoid interfering with the load ground path
• Includes two uncommitted comparators for system protection logic
• Offers a dedicated 1.21V reference output pin

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 the specific suffix 'BETE' against the official manufacturer datasheet to confirm the exact gain option and temperature grade, as these parameters define the electrical performance. Confirm availability status through authorized distributors, as supply levels may be restricted or limited. Ensure the 16-TQFN footprint matches the target PCB design requirements before finalizing procurement.

Current Regulation/Management Selection Notes

Select this component when precise high-side power monitoring is required without disrupting the system ground. The ±0.5% accuracy makes it suitable for applications demanding reliable overload detection. Consider the 16-TQFN package size for space-constrained designs. Evaluate the need for the integrated comparators and reference voltage to potentially reduce external component count in the final circuit architecture.

Current Regulation/Management Part Context

This part belongs to the MAX4210/MAX4211 family of low-cost, low-power monitors. While the MAX4210 focuses on current and power sensing, the MAX4211 variant adds functional blocks such as uncommitted comparators and a reference output. This family is designed for battery-powered systems where ground path interference must be minimized.

Current Regulation/Management Replacement Considerations

The MAX4210EEUA+ serves as a related alternative within the same family but utilizes an 8-pin µMAX/uSOP package and lacks the comparator and reference features found in the MAX4211 series. Verify pinout compatibility and feature requirements before substituting.
