MAX34406HETG+T

Current Regulation/Management Overview

The MAX34406HETG+T is a quad current sense monitor manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features four precision current sense amplifiers with a fixed gain of 100 V/V. The device supports a common-mode voltage range from 2 V to 28 V and offers a high common-mode rejection ratio of 120 dB. Input offset voltage is specified at 100 uV, with a gain error of 0.6%. It operates within a temperature range of -40°C to +85°C and is housed in a 24-lead TQFN package.

Current Regulation/Management Feature Summary

• Integrates four independent precision current sense amplifiers for simultaneous multi-rail monitoring
• Provides fixed gain options including 100 V/V to simplify signal conditioning for external ADCs
• Includes built-in overcurrent comparators with a 1.0 V threshold and logic OR output for fault protection

Current Regulation/Management Applications

• Base station power distribution systems
• Industrial control equipment monitoring
• Network switch and router power management
• Server blade current sensing
• Smart grid infrastructure monitoring

Current Regulation/Management Procurement Notes

Verify the suffix 'H' indicates the specific gain variant (100 V/V) as defined in the official datasheet. Confirm RoHS compliance status via the manufacturer's documentation. Ensure the TQFN-24 package dimensions match the design footprint requirements. Cross-reference the part number with the latest Analog Devices catalog to confirm availability and lead times through authorized distributors.

Current Regulation/Management Selection Notes

Select this component when designing systems requiring precise measurement of multiple current rails with high common-mode voltages up to 28 V. The 100 V/V gain option is suitable for applications where the differential input voltage is small relative to the common-mode level. Consider the 24-pin TQFN package for space-constrained PCB layouts. Ensure the operating temperature range meets the environmental specifications of the target application.

Current Regulation/Management Part Context

The MAX34406 belongs to the MAX34406 series of quad current sense monitors. This family provides integrated solutions for high-side current sensing in complex electronic systems. The HETG+T designation specifies the 100 V/V gain version in a tape-and-reel packaging format. It complements other Maxim Integrated analog components used in power management and signal conditioning circuits.

Current Regulation/Management Replacement Considerations

Check for MAX34406FETG+T (25 V/V), MAX34406METG+T (50 V/V), or MAX34406WETG+T (200 V/V) if different gain values are required. Verify pinout compatibility before substitution. Consult the official datasheet for any functional differences between gain variants.
