ROHM Semiconductor BM1ZxxxFJ Evaluation Boards

ROHM Semiconductor BM1ZxxxFJ Evaluation Boards provide a demonstration platform for the BM1ZxxxFJ AC Voltage Zero Cross Detection (ZCD) ICs. The BM1ZxxxFJ ZCD ICs are voltage comparators that output the AC voltage zero-cross timing detection and the DC voltage after diode rectification. By eliminating the need for photocouplers and external components required in conventional ZCD circuits, it is possible to reduce the number of parts drastically and realize compact and highly reliable power supply applications.
