BM1Z101FJ-E2 ROHM

Datasheet 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. SOP-J11 8.65 mm x 6.00 mm x 1.65 mm Pitch (Typ): 1.27 mm Features AC Zero Cross Detection Function Eliminates Photocoupler 600 V High Voltage Monitor Handle both Normal and Double Rectification 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 Washing Machine, Air-conditioner Typical Application Circuit Motor AC/DC Filter BM2P Series DC/DC Motor BM1Z101FJ Others BD9E Series Driver -Com Product structure : Silicon integrated circuit This product has no designed protection against radioactive rays .w ww.rohm.com TSZ02201-0F1F0A200370-1-2 2017 ROHM Co., Ltd.
