Datasheet AC Voltage Zero Cross Detection IC BM1Z001FJ General Description 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.
Furthermore, this IC can handle both normal and double rectification by the original system.
