MAX34406WETG+

Current Regulation/Management Overview

The MAX34406WETG+ is a quad current sense monitor manufactured by Analog Devices Inc./Maxim Integrated. It features four independent channels with selectable gains of 25 V/V, 50 V/V, 100 V/V, and 200 V/V. The device operates with a common-mode voltage range of 2 V to 28 V and offers a common-mode rejection ratio of 120 dB. Key electrical parameters include an input offset voltage of 100 uV, a gain error of 0.6%, and a 3dB bandwidth of 125 kHz. It functions within a temperature range of -40°C to +85°C and is housed in a TQFN-24 package.

Current Regulation/Management Feature Summary

• Integrates four independent high-side current sense amplifiers for multi-rail monitoring
• Provides programmable gain options to accommodate various shunt resistor values
• Ensures high accuracy through low input offset voltage and minimal gain error

Current Regulation/Management Applications

• Multi-rail power distribution units
• Server and storage system power management
• Industrial equipment current monitoring

Current Regulation/Management Procurement Notes

Verify the specific suffix 'W' against official datasheets to confirm pinout and thermal characteristics differ from standard variants. Confirm RoHS compliance status via manufacturer documentation. Ensure the TQFN-24 package matches PCB footprint requirements. Validate operating temperature range suitability for the target environment.

Current Regulation/Management Selection Notes

Select this component when simultaneous monitoring of multiple voltage rails is required. The quad configuration reduces board space compared to discrete solutions. Verify that the 28V common-mode limit exceeds the highest rail voltage. Consider the 125kHz bandwidth for dynamic load response requirements.

Current Regulation/Management Part Context

This part belongs to the MAX34406 series of current sense monitors. It is designed for applications requiring precise measurement of current across multiple power domains. The device integrates precision amplifiers and reference components to simplify design.

Current Regulation/Management Replacement Considerations

Check for MAX34406TETG+ or other suffix variations within the same family for pin-compatible alternatives. Verify functional equivalence regarding gain settings and package dimensions before substitution.
