REFACDC040 - Reference Design

AC voltage detection zero-cross IC High precision DC voltage output type

BM1Z102FJ-EVK-001 is equipped with BM1Z102FJ. This evaluation board outputs a zero cross signal from 90 Vac to 264 Vac input.

  • This evaluation board is mounted with BM1Z102FJ which outputs high precision zero cross timing of targeted AC voltage
  • and the DC voltage after diode rectification with high accuracy.
  • The evaluation board is also mounted with power supply for the IC.
