Datasheet AC Voltage Zero Cross Detection IC BM1Z102FJ BM1Z103FJ 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. Package W (Typ) x D (Typ) x H (Max) Features SOP-J11 8.65 mm x 6.0 mm x 1.65 mm AC Zero Cross Detection Function Pitch (Typ): 1.27 mm Eliminates Photocoupler 600 V High Voltage Monitor Modifiable Zero Cross Delay Time n Channel Open Drain Output DC Voltage Monitor Function 600 V High Voltage Monitor VCC Under Voltage Locked Out (VCC UVLO) Applications Household Appliances such as Rice Cooker and Dryer, etc. Lineup Product Name ACOUT Pin Output Waveform BM1Z102FJ Pulse BM1Z103FJ Edge Typical Application Circuit Motor AC/DC Filter BM2P Series DC/DC Motor BM1Z10xFJ Others BD9E Series Driver -Com Product structure : Silicon integrated circuit This product has no designed protection against radioactive rays .w ww.rohm.com TSZ02201-0F1F0A200610-1-2 2019 ROHM Co., Ltd.
