Maxim Integrated MAX4073TAUT High-Side Current-Sense Amplifier

The MAX4073TAUT from Maxim Integrated is a precision, high-side current-sense amplifier designed to monitor the current flow in battery-powered devices, industrial control systems, and automotive applications. This compact and efficient device is capable of providing accurate current measurement by sensing the voltage drop across a shunt resistor placed in the path of the high-side supply line.

Featuring a wide input common-mode voltage range of 4V to 28V, the MAX4073TAUT can operate in a variety of systems without the need for external components to shift the input voltage range. This makes it an ideal choice for systems that experience large variations in supply voltage. The device is also capable of handling transient voltages up to 36V, offering additional protection against voltage spikes and surges that are common in automotive and industrial environments.

The MAX4073TAUT offers a fixed gain of 20V/V, providing a convenient output voltage scaling for easy interfacing with analog-to-digital converters (ADCs) or microcontrollers. With its precision accuracy, the device ensures reliable current measurement, which is critical for system diagnostics, battery management, and power monitoring.

One of the key features of the MAX4073TAUT is its low input offset voltage, which minimizes error in current measurement and enhances overall system accuracy. Additionally, the device boasts a low quiescent current, which is particularly beneficial for battery-powered applications where power conservation is crucial.

The MAX4073TAUT is available in a compact SOT23-6 package, making it suitable for space-constrained applications. It is also fully specified over the -40°C to +125°C temperature range, ensuring reliable operation in extreme temperature environments.

With its combination of high accuracy, wide input voltage range, and robust transient voltage tolerance, the MAX4073TAUT from Maxim Integrated is a versatile and reliable solution for high-side current sensing in a broad range of applications.
