BM1Z102FJ
AC Voltage Zero Cross Detection IC

This IC outputs the AC voltage zero cross timing detection and the DC voltage after diode rectification 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.
