The MAX4374HEUB+T from Maxim Integrated is a high-precision, low-power current-sense amplifier that is ideal for a wide range of applications requiring current monitoring. This integrated circuit (IC) is designed to provide accurate current measurement for system monitoring and control in portable devices, battery management systems, power supplies, and motor control applications.
Featuring a high-side current-sense amplifier, the MAX4374HEUB+T is capable of measuring the voltage across a current-sense resistor placed in the power line while maintaining a high level of electrical isolation between the power path and the measuring circuit. This is particularly useful in systems where ground disturbance cannot be tolerated.
The device offers a fixed gain of 20V/V, which simplifies the design process by eliminating the need for external gain-setting components. Its precision specifications include a low input offset voltage and a tight gain accuracy, ensuring reliable performance in critical applications. The MAX4374HEUB+T operates over a wide supply voltage range of 2.7V to 28V, making it versatile for use in both low and high-voltage systems.
The MAX4374HEUB+T comes in a small, 10-pin µMAX package, which is highly space-efficient and suitable for compact PCB layouts. Its extended temperature range of -40°C to +85°C allows for operation in harsh environments, ensuring consistent performance across various temperature conditions.
Key features of the MAX4374HEUB+T include its low power consumption, which is critical for battery-powered applications, and its high accuracy, which ensures precise current monitoring. The device also includes a filter pin for external low-pass filtering, allowing designers to tailor the bandwidth to specific application needs.
Overall, the MAX4374HEUB+T is a robust and reliable solution for designers looking to implement accurate current sensing in their systems with minimal design complexity and maximum efficiency.
