            S-576Z B Series ZCL™ Hall Effect ICs
                    ABLIC's ZCL (Zero Crossing Latch) Hall effect ICs transform the brushless DC motor market
    

ABLIC’s ZCL Hall effect IC is a latch-type Hall effect IC that uses a new detection method that detects the output signal at the zero-crossing point where polarity changes. It is ideal for BLDC motor control, and unlike other Hall effect ICs, it is not thrown off by variations in magnetic flux density and can maintain stable detection. The high energy efficiency, reliability, low noise performance, and other characteristics make it ideal for consumer products requiring granular control.
