Maxim Integrated's MAX9926UAEE/V+T Variable Reluctance Sensor Interface

Maxim Integrated's MAX9926UAEE/V+T is a high-performance, dual-channel variable reluctance sensor interface designed for automotive and industrial applications. This precision device is specifically engineered to provide robust solutions for processing signals from magnetic sensors that measure crankshafts, camshafts, and transmission speed in internal combustion engines and electric motors.

The MAX9926UAEE/V+T offers unparalleled flexibility and reliability, featuring dual differential sensor inputs that are compatible with a wide range of sensor types, including single-ended and differential variable reluctance sensors, as well as Hall-effect and AMR sensors. This versatility makes it an ideal choice for designers looking to create systems that require accurate position or speed sensing.

Key features of the MAX9926UAEE/V+T include its adaptive peak threshold and hysteresis, which automatically adjust to accommodate a wide range of sensor amplitudes and air-gap variations. This ensures consistent and accurate sensing even under fluctuating conditions. The device also boasts an integrated adaptive peak threshold, which minimizes the effects of system noise and improves signal-to-noise ratio, leading to more precise measurements.

With its wide operating voltage range of 4.5V to 5.5V and an extended temperature range of -40°C to +125°C, the MAX9926UAEE/V+T is built to perform reliably in harsh environments. The device is packaged in a compact 16-pin QSOP, making it suitable for space-constrained applications.

For added convenience, the MAX9926UAEE/V+T includes two open-collector outputs that can directly drive electronic control units (ECUs) with digital signals. Additionally, the device features robust electrostatic discharge (ESD) protection, safeguarding the interface against voltage spikes and ensuring long-term stability and performance.

Whether used in automotive engine management systems, transmission controllers, or industrial motor control applications, Maxim Integrated's MAX9926UAEE/V+T offers a high-quality, reliable solution for processing variable reluctance sensor signals.
