Note 1: VTH is set at 2.0V and hysteresis voltage at 90mV.
1. Use a resistor to divide the detected voltage so that it equals V
TH
when monitoring regulator
primary side power supply.
2. When monitoring AC voltage rectified as in the application circuit, set so that it equals V
TH
by
lowering the constant and dividing with a resistor. Refer to application circuit diagram.
Note 2: VAC input and VS1 are OR, so either signal makes CE low when power outage is detected.
