non-isolated ac voltage detection zero crossing
non-isolated type, the bm1z002fj-evk-001 outputs a signal indicating when there is a zero voltage crossing from an input ac voltage from 90vac to 264vac.
- 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.
