MODE
MODE is a tri-state input pin for operation mode selection.
See the following table 2.
Override Control (for PT8A2621 only): The term override re-
fers to the change of operating mode by switching the power
switch twice within 3 seconds. When the chip is working in the
AUTO mode (MODE pin openned), the output is activated by
a valid PIR trigger signal and the output active duration is con-
trolled by the OSCD oscillation period. The lamp can be switched
to ON from the AUTO mode by either switching the MODE pin
to V
CC or switching the power switch twice within 3 seconds.
The device can be toggled from ON to AUTO by switching the
power switch twice within 3 seconds again (override opera-
tion).
If the chip is overridden to ON and there is no further override
operation, it will return to AUTO automatically after an inter-
nal preset ON time duration (8 hours).
Note:Flash is only for the TRIAC Rev.
RST Pin
RST is used to reset the device. It is internal pull-high and
active low. The use of C
RST can extend the power-on initial
time. If the RST pin is openned (without CRST), the initial
time is 40 seconds. See Figure 6.

Description
V
CC
ON
Output is always ON: RELAY pin sends high level for relay driving; TRIAC pulse train output is
synchronized by ZC for triac driving.
GND
OFF
Output is always OFF: RELAY pin sends low level for relay driving; TRIAC pin sends high level
for triac driving.
Open
AUTO
Outputs remain in the OFF state until activated by a valid PIR trigger input signal. When working
in the AUTO mode, the device allows override control by switching the ZC signal.
