isolated ac voltage detection zero crossing
bm1z002fj-evk-002 outputs zero-crossing signals from 90 vac to 264 vac inputs. the evaluation board is mounted with bm1z002fj which outputs hight precision zero cross timing of targeted ac voltage.
- bm1z002fj will provide power less down to 1/10 of what conventional zwro cross signal generator circuit consumed.
- the evaluation board is also mounted with power supply for the ic.
