AC Voltage Zero Cross Detection IC

This evaluation board outputs a signal indicating when there is a zero voltage crossing from an input AC voltage from 90 VAC to 264 VAC. The BM1Z002FJ with the very few external components, will output a signal which is synchronous and offset in time if configured to do so, indicating when the two phases of the input AC signals are crossing 0V relative to one another. The advantage of the BM1Z002FJ is that it will provide the desired output signal while consuming less than 1/10 of the current, using fewer components, and at higher precision and repeatability as compared to a conventional zero cross detection circuit
