AC Voltage Zero Cross Detection By monitoring the voltage between the VH_AC1 and VH_AC2 pins, this IC outputs the zero cross point of AC voltage from the ACOUT pin. These pins have a built-in monitor circuit that tolerates 600 V and they realize high reliability and low power consumption. The ACOUT pin performs an n channel open drain output and this makes it possible to support various applications. It is necessary for the VH_AC1 pin to be connected to the N side of the AC input and for the VH_AC2 pin to be connected to the L side of the AC input.

Start Sequence A: B: C: D: E: AC Input voltage is applied. When the VCC pin voltage becomes more than VUVLO1, the IC starts to operate. The VH_AC1 and VH_AC2 pins voltage in 1st cycle is detected after the IC starts operation. The VH_AC1 and VH_AC2 pins voltage in 2nd cycle is detected and the internal arithmetic of IC is completed. After the arithmetic, the first positive edge point of the ACOUT pin voltage is detected. After that, the IC repeats the high-to-low pulse operation at the zero cross points. (The zero cross detection function starts to operate at 3rd cycle from starting IC’s operation.) www.rohm.com © 2019 ROHM Co., Ltd. All rights reserved.

Noise Filter 1 (tAC1): In case of the ACOUT pin voltage = Hiz, signals of pulse width < tAC1 is not accepted. Pin B, the P-N junction operates as a parasitic diode. When GND > Pin B, the P-N junction operates as a parasitic transistor. Parasitic diodes inevitably occur in the structure of the IC. The operation of parasitic diodes can result in mutual interference among circuits, operational faults, or physical damage. Therefore, conditions that cause these diodes to operate, such as applying a voltage lower than the GND voltage to an input pin (and thus to the P substrate) should be avoided.

Example of IC Structure 11. Ceramic Capacitor When using a ceramic capacitor, determine a capacitance value considering the change of capacitance with temperature and the decrease in nominal capacitance due to DC bias and others. 12. Thermal Shutdown Circuit (TSD) This IC has a built-in thermal shutdown circuit that prevents heat damage to the IC. Normal operation should always be within the IC’s maximum junction temperature rating. If however the rating is exceeded for a continued period, the junction temperature (Tj) will rise which will activate the TSD circuit that will turn OFF power output pins. When the Tj falls below the TSD threshold, the circuits are automatically restored to normal operation. Note that the TSD circuit operates in a situation that exceeds the absolute maximum ratings and therefore, under no circumstances, should the TSD circuit be used in a set design or for any purpose other than protecting the IC from heat damage. 13. Over Current Protection Circuit (OCP) This IC incorporates an integrated overcurrent protection circuit that is activated when the load is shorted. This protection circuit is effective in preventing damage due to sudden and unexpected incidents. However, the IC should not be used in applications characterized by continuous operation or transitioning of the protection circuit. www.rohm.com © 2019 ROHM Co., Ltd. All rights reserved.
