BM1Z002FJ-E2 ROHM

Datasheet AC Voltage Zero Cross Detection IC BM1Z002FJ BM1Z003FJ General Description Key Specifications This IC outputs the AC voltage zero cross timing VCC Input Power Supply Voltage Range: detection with high accuracy. -0.3 V to +29 V By eliminating the need for photocoupler and external VH AC1 and VH AC2 Pins Operation Voltage: components required in conventional applications, it is 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-J7S 4.9 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 VCC Under Voltage Locked Out (VCC UVLO) Applications Household Appliances such as Rice Cooker and Lineup Dryer, etc. Product Name ACOUT Pin Output Waveform BM1Z002FJ Pulse BM1Z003FJ Edge Typical Application Circuit Motor Filter AC/DC BM2P Series DC/DC Motor Others BD9E Series Driver BM1Z00xFJ -Com Product structure : Silicon integrated circuit This product has no designed protection against radioactive rays. www.rohm.com TSZ02201-0F1F0A200600-1-2 2019 ROHM Co., Ltd.
