Relays are used to connect, or disconnect, ring generators to-and-from telephone lines. If the two points are at different potentials, there are high-current transients at the moment of contact. This ...

Rohm recently introduced a low-power 600V-tolerant zero-crossing detection chip, intended to cut energy wastage in home appliances by reducing sense current through the high voltage monitoring ...

The rising demand for smart appliances and IoT applications has added communication functionality (i.e. Wi-Fi) to home appliances. As it is necessary for such devices to always be ON to maintain ...

This application note shows the user how to implement a zero cross detector with a minimum of external components. It should be noted that this solution will not give any galvanic isolation for the ...

This design idea explains how a zero-crossing detector circuit can be used to control triacs. Fig 1. This zero-crossing detector circuit generates the control pulses needed to turn on triacs that ...

ROHM’s BM1ZxxxFJ integrated zero-cross detection IC series is optimized for home appliances such as vacuum cleaners, washing machines, and air conditioners. The rising demand for smart home devices ...
