Maxim Integrated MAX4173FEUT High-Side Current-Sense Amplifier

The MAX4173FEUT from Maxim Integrated is a precision, high-side current-sense amplifier that is designed to monitor the current through a shunt resistor in various applications. This compact and efficient device is ideal for portable and space-constrained applications due to its small footprint in a SOT23-6 package. The MAX4173FEUT operates over a wide supply voltage range from 4.5V to 76V, making it versatile for use in systems with varying power levels.

Featuring a high accuracy of 3% max over temperature, the MAX4173FEUT ensures reliable current measurements in your system. Its low input offset voltage minimizes error, which is crucial in precision applications. The device has a high input common-mode voltage range of 0V to 76V, independent of the supply voltage, allowing it to function in high-side current-sensing applications without the need for a high-side driver or level shifter.

The MAX4173FEUT comes with a gain of 20V/V, which translates the voltage across the shunt resistor into a proportional output voltage. This makes it easy to interface with analog-to-digital converters (ADCs) or microcontrollers for digital processing. Its quiescent current is also minimal, making it suitable for power-sensitive applications.

With its integrated precision current-sense amplifier, the MAX4173FEUT is commonly used in a variety of applications, including battery management, power management, and overcurrent protection circuits. It is particularly useful in systems that require accurate current monitoring, such as in battery chargers, smart battery packs, and power supplies. Additionally, its ability to operate at high voltages makes it suitable for automotive and industrial applications where higher voltage levels are prevalent.

Overall, the Maxim Integrated MAX4173FEUT is a reliable, accurate, and easy-to-use solution for high-side current sensing. Its compact size, wide voltage range, and precision make it an excellent choice for designers looking to enhance their system's safety and efficiency by accurately monitoring current flow.
