    The SYCT-3 is a family of high accuracy galvanically isolated Hall-effect current sensor ICs for ±50A to ±250A. Current sensing supports both unidirectional and bidirectional, DC and AC currents. Applied current generates a magnetic field, then converted into a proportional analog voltage. The bandwidth is up to 170kHz and the response time is 3μs. 

    The SYCT-3 provides a ratiometric or fixed zero current output for differential measurements. A precise, proportional output voltage is achieved by the high accuracy, good linearity, low temperature drift Hall IC, which is programmed for accuracy at the factory. 

    The package offers four options, PFF/PSF/PSS/SMT, for easy implementation, which the PFF is the standard package.

    The SYCT-3 is suitable for insulation, small size with low heat generation applications, including automotive, industrial, and communications systems.
