The MAX9634TERS+ is a precision, low-power, low-voltage, high-side current-sense amplifier from Maxim Integrated, a leader in analog and mixed-signal products. Designed for a broad range of applications, this component provides an accurate current measurement solution for systems requiring battery or power monitoring, power management, and protection circuits.

With its tiny 4-bump UCSP (ultra-small chip-scale package) or 5-pin SOT23 package, the MAX9634TERS+ is an ideal choice for space-constrained applications. It operates over a wide supply voltage range of 2.7V to 5.5V, making it versatile for both portable and fixed power supply designs. This high-side current-sense amplifier is capable of sensing the voltage across shunt resistors over a wide common-mode range from 0.1V to 28V, independent of the supply voltage.

The MAX9634TERS+ offers a precision input offset voltage of just 250µV (max) and an ultra-low 1µA (typical) supply current. This combination of features ensures accurate current measurement with minimal impact on overall power consumption. The device also features a gain of 25V/V, which enhances the ability to detect low-level current changes in high-side sensing applications.

Safety and reliability are paramount in any power monitoring system, and the MAX9634TERS+ addresses this with its integrated ESD protection circuitry. It is specified for the extended -40°C to +125°C temperature range, which allows for operation in harsh environments, and is RoHS compliant, adhering to environmental standards.

Whether it's being used in battery management systems, power supply monitoring, portable devices, or any system that requires precise current monitoring, the MAX9634TERS+ from Maxim Integrated provides a compact, accurate, and energy-efficient solution for high-side current sensing needs.
