CS8191XDWF20

Sensor And Detector Interfaces Overview

The CS8191XDWF20 is a precision air-core tachometer and speedometer driver manufactured by onsemi. Designed specifically for driving four-quadrant air-core meter movements, the integrated circuit incorporates an input comparator to sense frequency signals such as vehicle speed or engine RPM. It features a charge pump for frequency-to-voltage conversion, a bandgap reference for stable operation, and a function generator with sine and cosine amplifiers that differentially drive motor coils. The device supports wide output voltage ranges and includes fault protection mechanisms against overvoltage and short circuits.
