Datasheet BM1Z102FJ, BM1Z103FJ (Rohm) - 6

BM1Z102FJ BM1Z103FJ 1. AC Voltage Zero Cross Detection – continued 1.2 VH_AC1 Pin UVLO
In case that the peak voltage of the VH_AC1 pin is VACUVLO or less, the ACOUT pin voltage is defined as Hiz. VH_AC1 – GND VACUVLO Voltage 0 V HiZ ACOUT – GND Voltage Low Figure 5. VH_AC1 Pin UVLO
1.3 VH_AC1 and VH_AC2 Pins Noise Filter
This IC has two noise filters. Noise Filter 1 (tAC1): In case of the ACOUT pin voltage = Hiz, signals of pulse width < tAC1 is not accepted. <tAC1 VH_AC1 – GND Voltage VH_AC2 – GND Voltage 0 V HiZ ACOUT – GND Voltage Low Figure 6. VH_AC1 and VH_AC2 Pins Noise Filter 1 Noise Filter 2 (tAC2): In case of the ACOUT pin voltage = Low, signals of pulse width < tAC2 is not accepted. <tAC2 VH_AC1 – GND Voltage VH_AC2 – GND Voltage 0 V HiZ ACOUT – GND Voltage Low Figure 7.
