Description
2611 2621
1
GND
Ground Ground
2
RELAY
O
RELAY drive output through an external NPN transistor, active high
2
TRIAC
O
TRIAC drive two-pulse 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
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
Mode select, connecting to V
CC
- output always on, connection GND - output always off,
open - auto detection
8
V
CC
Power
Power supply
9
V
EE
O
Internal voltage regulator output, 3.6V with respect to ground. Connected to the drain of
PIR sensor
10
RST
I
Chip reset input, active low, kept floating or connected an RC network
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
O
Output of first operational amplifier
14
OP2P
I
Non-inverted input of second operational amplifier.
15
OP2N
I
Inverted input of second operational amplifier
16
OP2O
O
Output of second operational amplifier
