Datasheet AC Voltage Zero Cross Detection IC
BM1Z102FJ BM1Z103FJ General Description Key Specifications VCC Input Power Supply Voltage Range:
-0.3 V to +29.0 V VH_AC1 and VH_AC2 Pins Operation Voltage:
600 V (Max) VH_DC Pin Operation Voltage:
600 V (Max) Circuit Current at Standby:
50 µA (Typ) Circuit Current at Operation:
160 µA (Typ) Operating Temperature Range:
-40 °C to +105 °C 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. Package
