MAX4210FETT+T

Current Regulation/Management Overview

The MAX4210FETT+T is a high-side power and current monitor featuring a 6-TDFN (3x3) package. It provides an analog output voltage proportional to load power by multiplying source voltage and current. Key electrical parameters include a +4V to +28V input source voltage range, a +2.7V to +5.5V power-supply voltage range, and a bandwidth of 220kHz. The device offers ±1.5% maximum accuracy for both current-sense and power-sense measurements. Supply current is specified at 380µA.

Current Regulation/Management Feature Summary

• Integrates an internal 25:1 resistor divider network to minimize external component count
• Utilizes high-side current-sense amplification to avoid interfering with the load ground path
• Provides an analog output voltage directly proportional to the power consumed by the load

Current Regulation/Management Applications

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

Current Regulation/Management Procurement Notes

Verify the specific suffix 'FETT' corresponds to the 6-TDFN (3x3) package and tape-and-reel configuration. Confirm that the '+T' designation indicates lead-free status and RoHS compliance as per Analog Devices standards. Ensure the operating temperature range aligns with system requirements, typically -40°C to +85°C for this series. Cross-reference the manufacturer part number with official distributor catalogs to confirm availability and authenticity before procurement.

Current Regulation/Management Selection Notes

Select this component when space-constrained designs require integrated high-side monitoring without external dividers. The 220kHz bandwidth supports dynamic load applications. Consider the ±1.5% accuracy limits for precision requirements. Evaluate the 380µA supply current against total system power budgets. The single-channel architecture suits individual rail monitoring rather than multi-rail simultaneous tracking.

Current Regulation/Management Part Context

This device belongs to the MAX4210 family of low-cost, low-power monitors. It shares functional similarities with the MAX4211, which adds uncommitted comparators and a reference output. The FETT variant specifically denotes the surface-mount TDFN packaging optimized for compact PCB layouts in portable and industrial electronics.

Current Regulation/Management Replacement Considerations

The MAX4211 serves as a functional substitute if comparator outputs or a reference voltage are required. Verify pin compatibility and package dimensions when substituting. Review datasheet differences regarding gain options and additional features to ensure system requirements remain met.
