The ZCL™ Hall Effect ICs transform the brushless DC motor market

A ZCL (Zero Crossing Latch)zero crossing latch Hall effect IC, is a latch type Hall effect IC that uses a world’s first detection method, by detecting 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.
