Descriptions
Output of the first stage OP amplifier.
Non-inverting input of the first stage OP amplifier.
Inverting input of the first stage OP amplifier.
Reference voltage output.
Ground.
Time Base. A RC oscillaror is connected on this pin.
Typical frequency is 30kHz.
No connection.
Time control input. A RC oscillator is connected on this
pin. It controls the delay time of the light.
Triac control pin. Active low.
Relay control pin. Active hight.
Zero-crossing input. It detects the zero-crossing point of
the AC line. The ouput of TRIAC pin is synchronous to this
pin.
Walk-Test function enable/disable. Internal pull low. The
walt-test function is disbled when this pin is high level.
Night and day detection enable/disable. Internal pull low.
The night-and-day detection is disbled when this pin is
high level.
Power supply.
Connect a photo-sensitive resistor to detect night time
and day time. If the input level is lower than 1.2V, it is
day time. If the input level is higher than 1.9V, it is night
time.
Inverting input of the second stage OP amplifier.
Non-inverting input of the second stage OP amplifier.
Output of the second stage OP amplifier.
* WT8076N16P1 and WT8076S16P1 : Walk-Test and Night&Day function is always enabled.
