MAX34411ETG+T

Overview

The MAX34411ETG+T is a quad current sense monitor manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2.7V to 5.5V and features an I²C-compatible serial interface for configuration and data readout. The device provides four independent current sensing channels with integrated programmable gain amplifiers. Key electrical parameters include a maximum input common-mode voltage of 60V, a typical accuracy of 1% over temperature, and a shutdown current of less than 1µA. It is housed in a 24-pin TQFN package measuring 4mm x 4mm.

Feature Summary

• Integrates four independent current monitoring channels with high-side sensing capability
• Features an I²C-compatible serial interface for digital control and data access
• Includes programmable gain amplifiers to accommodate various shunt resistor values
• Provides fault detection and reporting capabilities through the serial interface

Applications

• Server and storage system power distribution monitoring
• Industrial equipment current regulation and protection
• Telecommunications infrastructure power management
• Battery-powered systems requiring precise current tracking

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lead-free packaging specifications prior to procurement. Ensure the ordering suffix matches the required tape-and-reel quantity. Check for any recent product change notices that may affect pin compatibility or electrical characteristics.

Selection Notes

Select this component when multiple independent current monitoring channels are required in a compact footprint. Evaluate the input common-mode voltage range against the highest potential rail in the circuit. Consider the I²C address configuration options if multiple devices share the same bus. Verify that the package thermal performance meets the application's dissipation requirements.

Part Context

This part belongs to the MAX34411 series of quad current monitors designed for multi-rail power management applications. It complements other Maxim Integrated power monitoring solutions by offering integrated signal conditioning and digital interfacing. The series targets designs requiring accurate current measurement across multiple power domains without external analog components.

Replacement Considerations

Check for MAX34411 variants with different package options or temperature grades. Verify functional compatibility with existing I²C addressing schemes. Confirm that alternative sources maintain the same 60V common-mode voltage rating and accuracy specifications.
