Maxim Integrated MAX4376HAUK+T High-Side Current-Sense Amplifier

The Maxim Integrated MAX4376HAUK+T is a precision, high-side current-sense amplifier designed to monitor the current flow in power supply and control systems. This versatile device offers a unique combination of features that make it ideal for a wide range of applications, including battery management, overcurrent protection, and power management in portable devices.

Equipped with a high-voltage input common-mode range from 0 to +28V, the MAX4376HAUK+T can accurately measure the current through a shunt resistor in systems operating at various voltage levels. This capability allows it to be used in both low and high-side current sensing configurations, providing valuable flexibility for system designers.

The device operates with a single supply voltage, ranging from +2.7V to +28V, which makes it suitable for both battery-powered and line-powered applications. The MAX4376HAUK+T offers a fixed gain of 20V/V, providing a high output voltage without the need for external gain-setting components, simplifying the design and reducing the overall component count.

With its precision current mirror output, the MAX4376HAUK+T can drive an analog-to-digital converter (ADC) directly, enabling digital systems to monitor current flow with high accuracy. The device features a low input offset voltage, which minimizes error in current measurement, and a wide bandwidth of 200kHz, allowing it to respond quickly to changes in current flow.

The MAX4376HAUK+T comes in a compact 5-pin SOT-23 package, making it an excellent choice for space-constrained applications. Its small footprint and low power consumption are particularly beneficial in portable electronics where efficiency and size are critical.

In summary, the Maxim Integrated MAX4376HAUK+T is a high-performance current-sense amplifier that offers a combination of high accuracy, ease of use, and flexibility. Its robust feature set makes it an essential component for designers looking to implement reliable current sensing in their applications.
