Description
MAX471 Voltage Current Sensor
The MAX471 Sensor Module, is a versatile and powerful current sensing solution. The module incorporates an IC that accepts input voltages spanning from 3V to 36V, making it compatible with a wide range of power sources. With its precision sensing resistor and two securely connected Blue color terminals, the MAX471 ensures accurate and reliable current measurements. Specifically designed to measure currents up to 3 amps, the module employs a 35 milliohm shunt resistor to effectively channel the current for measurement. The RS- and RS+ pins are intelligently integrated into these terminals, enhancing the module's connectivity and usability. By amplifying the voltage drop across the shunt, the MAX471 delivers a highly amplified and dependable signal through the OUT pin, facilitated by its four-pin configuration. Importantly, regardless of the current direction, the voltage output at the OUT pin remains consistently positive. This module is the ideal choice for applications requiring precise current monitoring and control, such as battery management systems, power supplies, motor control, and energy monitoring. With its wide input voltage range and advanced features, the MAX471 Sensor Module empowers engineers and enthusiasts to achieve optimal energy management and efficient current sensing in a vast array of electronic projects.Technical Details

Principle of Work:
The module uses high-side current sensing to measure current flow through a load or battery by detecting the voltage drop across a small internal resistor. The MAX471 includes a built-in 35mΩ sense resistor, while the MAX472 supports external resistors for higher currents. An internal amplifier boosts the voltage drop, converting it into a proportional output voltage. A single external resistor can be used for ground-referenced voltage conversion. The open-collector SIGN output indicates current direction, helping to determine charging or discharging states. Operating between 3V-36V, the MAX471 measures up to 3A, while the MAX472 supports higher currents.Applications
