Maxim Integrated MAX4376HAUK+ High-Side Current-Sense Amplifier

The MAX4376HAUK+ from Maxim Integrated is a precision, high-side current-sense amplifier designed to monitor the current flowing through a shunt resistor placed in the high-side of a power supply or in any other position where current monitoring is critical. This device is highly versatile and can be used in a variety of applications such as battery management systems, power management, and overcurrent protection circuits.

This current-sense amplifier is housed in a compact SOT-23 package, making it an excellent choice for space-constrained applications. It operates over a wide supply voltage range from 2.85V to 36V, which allows it to be used in both low and high voltage systems. The MAX4376HAUK+ is capable of sensing very small voltage drops across the shunt resistor, enabling the precise measurement of current even at low levels.

The MAX4376HAUK+ features a high accuracy with a low input offset voltage, which minimizes error in current measurements. It also offers a high gain accuracy which ensures consistent performance across the full operating temperature range. With a quiescent current of just 100µA, this current-sense amplifier is optimized for power-sensitive applications.

One of the key benefits of the MAX4376HAUK+ is its ability to reject common-mode voltage, which can range from 0V up to 28V, minimizing the impact of voltage spikes or dips on the accuracy of the current measurement. Additionally, the device boasts a fast response time, which is crucial for systems that require quick reaction to overcurrent conditions.

The MAX4376HAUK+ also includes integrated features such as a voltage output that is proportional to the current passing through the shunt resistor, making it easy to interface with analog-to-digital converters (ADCs) or microcontrollers for further processing. Its robust design ensures reliable operation even in harsh industrial environments.

Overall, the Maxim Integrated MAX4376HAUK+ is a high-performance solution for designers looking to implement precise current sensing in their projects, with the added benefits of a small footprint and low power consumption.
