Maxim Integrated MAX4173HEUT+T Current-Sense Amplifier

The MAX4173HEUT+T from Maxim Integrated is a high-quality, precision current-sense amplifier designed for a wide range of applications. This compact and efficient device offers a simple solution for current monitoring in both portable and non-portable applications, making it an essential component for power management systems.

With its tiny SOT23-6 package, the MAX4173HEUT+T is optimized for space-constrained applications, ensuring that it can be integrated into the most compact of designs without sacrificing performance. The device features a high-side current-sense, which allows it to measure the current flowing through a shunt resistor placed in the supply line while maintaining a ground-referenced output voltage. This method of current sensing is advantageous as it does not interfere with the ground path of the load being measured.

The MAX4173HEUT+T boasts a wide input common-mode voltage range from 3V to 28V, which makes it versatile for various supply voltages. It is capable of sensing both positive and negative currents, and its low input offset voltage (typically 250µV max) ensures accurate current measurements, even at low current levels. The device also features a high accuracy with a gain error of less than 1%, further enhancing its reliability in critical applications.

With a quiescent current of just 100µA, the MAX4173HEUT+T is an energy-efficient choice, making it ideal for battery-operated devices where power conservation is crucial. The amplifier is also fully specified over the -40°C to +125°C temperature range, which ensures stable performance in a variety of environmental conditions.

Applications for the MAX4173HEUT+T include but are not limited to battery management, overcurrent protection, power management in PCs and servers, and portable devices such as smartphones and tablets. Its robust design and precision make it a go-to component for engineers looking to implement accurate current sensing in their designs.

In summary, the Maxim Integrated MAX4173HEUT+T is a versatile and precise current-sense amplifier that offers excellent performance in a small package, suitable for a multitude of applications requiring current monitoring and power management.
