Maxim Integrated MAX4375FEUB+ High-Side Current-Sense Amplifier

The MAX4375FEUB+ is a precision high-side current-sense amplifier from Maxim Integrated, designed to provide accurate current measurement in a wide range of applications. This compact and efficient device is housed in a tiny 10-pin µMAX package, making it ideal for space-constrained applications where monitoring of current is essential for performance and reliability.

This high-side current-sense amplifier is capable of operating over a wide supply voltage range from 2.7V to 28V, which ensures compatibility with various system voltages and provides the flexibility needed for diverse applications. The MAX4375FEUB+ offers a fixed gain of 20V/V, allowing for easy integration into systems without the need for external gain-setting components.

One of the key features of the MAX4375FEUB+ is its ability to measure the voltage across shunt resistors at common-mode voltages from 0V to 28V, even in systems where the battery voltage can vary. This capability is particularly useful in battery-powered and automotive applications where the supply voltage can fluctuate significantly.

The device boasts a low input offset voltage of just 250µV (max), which enhances the accuracy of current measurements. This precision is crucial in applications such as battery charge and discharge monitoring, power management, and overcurrent protection circuits.

For added convenience, the MAX4375FEUB+ features a high accuracy of 0.5% (max) over the entire temperature range of -40°C to +85°C. This ensures reliable performance even in harsh environmental conditions. Additionally, the current-sense amplifier has a quick response time, which is vital for systems that require immediate action in response to current changes.

The combination of high accuracy, wide supply voltage range, and compact form factor makes the MAX4375FEUB+ an excellent choice for designers looking to implement current monitoring in portable devices, consumer electronics, and industrial systems. Its robust design and ease of use make it a go-to solution for current-sensing applications where space and precision are at a premium.
