Datasheet
AC Voltage Zero Cross Detection IC
BM1Z102FJ BM1Z103FJ
General Description
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.
