New Integrated Zero Cross Detection ICs Minimize Standby Power Consumption in Home Appliances

The BM1ZxxxFJ series supports both pulse and edge waveforms used in home appliance specifications, eliminating the need for software changes when replacing conventional zero cross detection circuits. 6 models are offered to ensure compatibility with a wide range of home appliances.

Evaluation Board

An integrated zero cross detection IC development board is available that integrates a power supply for driving ROHM’s integrated zero cross detection IC, facilitating device evaluation. This evaluation board is designed to simplify the decision-making process for designers when considering replacement of existing circuits using a photocoupler.

Terminology

Zero Cross Point

A zero cross detection circuit is needed in home appliances that supply power from an AC outlet to detect the zero cross point (which is the 0V point of the AC waveform) in order to efficiently control both motors and MCUs. As a result, improving zero cross detection accuracy allows for even more efficient motor and MCU control. And when the motor is stopped, pulse control provides greater circuit safety by reliably stopping the voltage at 0V.
