CS8191 Datasheet | Cherry Semiconductor Corporation

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 parator 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 petitive parts (CS289, and LM1819). It is protected against short circuit and overvoltage (60V) fault conditions.
