Maxim Integrated MAX9634TERS+T High-Side Current-Sense Amplifier

The Maxim Integrated MAX9634TERS+T is a precision, high-side current-sense amplifier designed to monitor current flow in various applications. This device is part of Maxim's range of analog ICs that provide accurate measurements for system monitoring and control. The MAX9634TERS+T is particularly well-suited for portable devices, battery management systems, and power management applications where space is at a premium and power efficiency is crucial.

This current-sense amplifier operates over a wide supply voltage range of 2.7V to 28V, making it versatile for use in both low and high voltage systems. Its precision is exemplified by its low input offset voltage of 10µV (typ) and high gain accuracy of ±0.5% (max), ensuring reliable and accurate current monitoring. The MAX9634TERS+T features a high voltage gain of 100V/V, which allows for the detection of small sense voltages over a large range of sensed currents.

One of the key features of the MAX9634TERS+T is its low quiescent current, consuming only 50µA (typ) which makes it ideal for battery-powered applications where power conservation is essential. The device also includes a shutdown feature that reduces the supply current to only 1µA (typ), further enhancing its suitability for power-sensitive applications.

The MAX9634TERS+T comes in a compact, 6-pin SOT-23 package, which minimizes the footprint on the PCB and is easy to integrate into a wide array of designs. The small package does not compromise its performance, as the device is designed to operate over the extended -40°C to +125°C temperature range, ensuring reliability and stability across various environments.

With its high accuracy, low power consumption, and compact form factor, the Maxim Integrated MAX9634TERS+T is an excellent choice for designers looking to implement current sensing in their next project with minimal impact on the overall system size and power budget.
