MAX4375HEUB - High-Side Current-Sense Amplifier from Maxim Integrated

The MAX4375HEUB from Maxim Integrated is a sophisticated, high-side current-sense amplifier designed for precision current measurement applications. This compact device is housed in a microMAX-10 package, making it an ideal choice for space-constrained applications such as portable devices, battery management systems, and power management circuits.

This current-sense amplifier is capable of monitoring the voltage across shunt resistors over a wide range of common-mode voltages, from 0V to as high as 28V, despite operating from a single 2.7V to 5.5V supply. This flexibility allows the MAX4375HEUB to be used in a variety of systems without the need for dual supplies, simplifying design and reducing overall system cost.

One of the key features of the MAX4375HEUB is its precision. It offers a low input offset voltage, which minimizes error in current measurement, and a high gain accuracy, ensuring reliable and consistent performance. Additionally, the device has a fast response time, making it suitable for overcurrent protection applications where quick reaction times are crucial.

The MAX4375HEUB also includes a current output that mirrors the high-side current, which is proportional to the voltage across the shunt resistor. This output can be connected directly to an ADC, allowing for easy digital monitoring of the current flow through the system. The device's low quiescent current helps to conserve power in battery-operated devices, further extending their operational life.

Installation and integration of the MAX4375HEUB are made easy with its industry-standard microMAX-10 package. The device's pinout is optimized for Kelvin connections to the sense resistor, reducing the impact of PCB trace resistance and ensuring accurate sensing.

In summary, the MAX4375HEUB is a high-quality, reliable current-sense amplifier that offers a combination of precision, flexibility, and ease of use for designers looking to monitor current in high-side configurations. Its robust feature set makes it an excellent choice for a wide range of applications, where accurate current monitoring is essential.
