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.
