BM1Z002FJ
AC Voltage Zero Cross Detection IC

This IC outputs the AC voltage zero cross timing detection with high accuracy. By eliminating the need for photocoupler and external components required in conventional applications, it is possible to reduce the number of parts drastically and realize compact and highly reliable power supply applications. In addition, this IC can reduce standby power largely in comparison with an existing photocoupler control.

Evaluation
Board

 
    • Evaluation Board
    • BM1Z002FJ-EVK-001
    • Non-Isolated Type. 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.
