MAX4004EUT+T

Current Regulation/Management Overview

The MAX4004EUT+T is a high-accuracy, high-side current monitor housed in a six-pin SOT-23 package. It operates on a supply voltage range of 2.7V to 22V and functions within an operating temperature range from -40°C to +85°C. The device provides a dynamic reference current range of 250nA to 2.5mA with better than 5% accuracy, while monitoring photodiode currents from 10nA to 10mA with reduced accuracy. It features internal current limiting of 20mA (typical) and thermal shutdown protection at +150°C.

Current Regulation/Management Feature Summary

• Provides a monitor output signal proportional to the reference current for precise measurement applications.
• Includes internal current limiting to protect against short circuits or excessive current conditions.
• Features a clamp diode to safeguard subsequent output circuitry from overvoltage events.
• Integrates thermal shutdown functionality to prevent damage when die temperature reaches critical levels.

Current Regulation/Management Applications

• Photodiode current monitoring systems
• Fiber optic applications
• Laboratory instrumentation
• Current-to-voltage conversion circuits

Current Regulation/Management Procurement Notes

Verify the specific suffix 'EUT' corresponds to the required tape-and-reel packaging format rather than tube packaging. Confirm that the component meets RoHS compliance standards for your region. Ensure the selected distributor supports the SOT-23 surface-mount footprint. Check for any lead-free manufacturing certifications required by your assembly process specifications.

Current Regulation/Management Selection Notes

Select this component when high-side monitoring of low-level currents is required within a wide voltage range. It is suitable for applications needing precise reference current tracking with minimal external components. Consider the thermal shutdown feature for environments with potential overheating risks. Evaluate the trade-off between accuracy and dynamic range for photodiode sensing tasks.
