ROHM Semiconductor USA, LLC Voltage Supervisors BM1Z102FJ-E2

The BM1Z102FJ-E2 is an AC voltage zero cross detection integrated circuit designed to provide high accuracy in detecting AC voltage zero crossing and outputting the corresponding DC voltage after diode rectification. This product eliminates the need for a photocoupler and reduces the number of external components required, leading to a more compact and reliable power supply solution. Key features include a 600 V maximum operation voltage for both AC and DC monitoring, a modifiable zero cross delay time, and a low standby current of 50 ¬µA. The device operates within a temperature range of -40 ¬8C to +105 ¬8C and comes in a SOP-J11 package measuring 8.65 mm x 6.0 mm x 1.65 mm. It is suitable for applications in household appliances such as rice cookers and dryers. Engineers considering this product should note its ability to significantly reduce standby power consumption compared to traditional photocoupler controls, making it a viable option for energy-efficient designs.
