Maxim Integrated MAX4372TESA High-Side Current-Sense Amplifier

The MAX4372TESA from Maxim Integrated is a high-accuracy, low-cost, high-side current-sense amplifier designed for a wide array of applications. This precision amplifier is especially suited for portable devices, battery management systems, and power management solutions, offering an efficient way to monitor current without interrupting the flow of power.

Featuring a unique input common-mode voltage range that operates from 2.7V to 28V, the MAX4372TESA is capable of functioning within a broad spectrum of supply voltages, making it versatile for use in both low and high-voltage systems. Its high-side measurement allows for the detection of current in systems where the ground is not accessible, or where isolation from the ground is required.

The device incorporates a precision current-sensing resistor, which enables it to convert a differential input voltage to a current output. This allows for easy interfacing with microcontrollers or analog-to-digital converters (ADCs) for current monitoring purposes. The MAX4372TESA comes in a space-saving 8-pin SOIC package, ideal for compact designs where board space is at a premium.

With a low quiescent current of just 30µA, this current-sense amplifier is optimized for power-sensitive applications. Additionally, it has a wide bandwidth of up to 200kHz, providing rapid response to current changes, which is critical for protecting circuits from overcurrent conditions.

The MAX4372TESA also features a high accuracy of ±1.5%, ensuring precise current measurement for reliable system performance. Its integrated gain resistor sets a fixed gain of 20V/V, simplifying the design process by eliminating the need for external gain-setting components.

Overall, the Maxim Integrated MAX4372TESA is an excellent choice for designers looking for an accurate, reliable, and easy-to-use high-side current-sense solution. Whether it's for overcurrent protection, battery charging, or power management, this amplifier provides a compact, efficient, and cost-effective option.
