AC Voltage Zero Cross Detection IC
BM1Z101FJ
General Description Key Specifications
This IC outputs the AC voltage zero cross timing VCC Input Power Supply Voltage Range:
detection and the DC voltage after diode rectification with -0.3 V to +29.0 V
high accuracy. VH_AC1 and VH_AC2 Pins Operation Voltage:
By eliminating the need for photocoupler and external 600 V (Max)
components required in conventional applications, it is VH_DC Pin Operation Voltage: 600 V (Max)
possible to reduce the number of parts drastically and Circuit Current at Standby: 50 A (Typ)
realize compact and highly reliable power supply Circuit Current at Operation: 160 A (Typ)
applications. In addition, this IC can reduce standby Operating Temperature Range: -40 C to +105 C
power largely in comparison with an existing
photocoupler control.
Furthermore, this IC can handle both normal and double
Package W (Typ) x D (Typ) x H (Max)
rectification by the original system.
