Description
1
GND
Ground Ground
2
TRIAC
O
TRIAC drive output: active negative pulse
3
OSCD
I/O
Output timing oscillator I/O: connected to an external RC to adjust output duration
4
OSCS
I/O
System oscillator I/O: connected to an external RC to set the system frequency. The
system frequency = 16kHz for normal application
5
ZC
I
Schmitt input for AC zero crossing detection
6
CDS
I
Analog Schmitt, connected to a CDS voltage divider for daytime/night auto-detection.
Low input to this pin can disable PIR input. CDS is a schmitt trigger input with 5-second
input debounce time.
7
MODE
I/O
Operating mode selection input:
V
CC: TEST mode for customer to quickly check function
GND: disable dimmer function
Open: Auto detection, MODE is square wave with 31.25Hz

O
Internal voltage regulator output: 3.6V with respect to ground. Connected to the
drain of PIR sensor
10
RELAY
O
RELAY driver output, active high
11
OP1P
I
Non-inverted input of first operational amplifier, connected directly to source of PIR
sensor
12
OP1N
I
Inverted input of first operational amplifier
13
OP1O
