CS8191 CS8191 Precision Air-Core Tach/Speedo Driver with Short Circuit Protection Description The CS8191 is specifically designed for use with 4 quadrant air-core meter movements. The IC includes an input comparator for sensing input frequency such as vehicle speed or engine RPM, 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 the motor coils. The CS8191 has a higher torque output and better output signal symmetry than other competitive parts (CS289, and LM1819). It is protected against short circuit and overvoltage (60V) fault conditions. Enhanced circuitry permits functional operation down to 8V.
