Maxim Integrated MAX4071ATA+T High-Side Current-Sense Amplifier

The Maxim Integrated MAX4071ATA+T is a precision, high-side current-sense amplifier that offers a compact and efficient solution for current monitoring in a wide range of applications. This amplifier is designed to detect the current flow in power supply circuits, battery management systems, and overcurrent protection circuits by measuring the voltage drop across a shunt resistor placed in the path of the high-side supply.

Key Features

• High-Side Sensing: The MAX4071ATA+T monitors the current flowing through a shunt resistor on the high side of the power supply, providing a safer and more convenient method for current sensing as it does not interfere with the ground path of the load circuit.
• Wide Input Common-Mode Range: It operates over a wide input common-mode voltage range from 4.5V to 76V, making it suitable for both low and high voltage systems.
• Low Quiescent Current: The device features a low quiescent current, which makes it an ideal choice for battery-powered and energy-sensitive applications.
• High Accuracy: With its precision design, the MAX4071ATA+T provides accurate current measurement, which is crucial for system diagnostics and protection.
• Compact SOT23 Package: The small SOT23 package allows for a space-saving PCB layout, which is essential for compact electronic designs.
