The PT8A264X is a CMOS LSI chip designed
for use in automatic PIR lamp control. It can operate
with a 2-wire configuration for triac applications or
with a 3-wire configuration for relay applications.
The chip is equipped with operational amplifiers, a
comparator, timer, a zero crossing detector, control
circuit, a voltage regulator, a system oscillator, and
an output timing oscillator.
Its PIR sensor detects infrared power variations
induced by the motion of a human body and
transforms it to a voltage variation. If the PIR output
voltage variation conforms to the criteria (refer to the
functional description), the lamp is turned on with an
adjustable duration. The PT8A264X offers three
operating modes (ON, AUTO, OFF) which can be set
through the MODE pin. While the chip is working in
the AUTO mode the user can override it and switch
to the quickly install mode, or manual ON mode, or
return to the AUTO mode by switching the power
switch.

Functional Description
VEE: supplies power to the analog front end circuit, it is about a stable 3.6V with respect to GND normally.
OSCS: a system oscillator input pin. System frequency of 16KHz can be generated when connecting to an external RC shows
as figure 2 (R=430K, C=180pf).

TD=23552/FOSCD
OSCD: input pin of timing oscillator. It’s connected to an external RC to obtain the desired output timer. Variable output turn-
on duration can be achieved by selecting various values of RC or using a variable resistor, see figure 3.
Note: The minimum resistor should be low enough to 2K in order to provide adjustable range about 1000 times between min
and max timer (The maximum resistor is 3M). It is recommended that CD is more than 103 in order to guarantee not too bad
linearity.
RELAY (TRIAC): an output pin set as a RELAY driving (active high) output for the PT8A2642/6/8, or as a TRIAC driving
(active low) output for the PT8A2641/5/7. The output active duration is controlled by the OSCD oscillating period.
CDS and CDSO: CDS has a schmitt trigger input structure. It is used to distinguish lighteness. With a resistor divider
including a CDS component, if light is weak enough, CDS is high the PIR input is active. Oppositely, the CDSO will be
inactive when CDS is low. The input debounce time from inactive to active is 5 seconds. CDS should be pulled high without
using this function. The input of CDS will be ignored once the output is active.
Figure 4 CDS input interface and enable debounce
RSTB: used to reset the chip. It is internal pull-high and active low.
The use of CRST can extend the power-on initial time. If the RSTB pin
is an open circuit (without CRST), the initial time is the default (40
secs).

PIR Sensor Light Switch
Power on initial: Because the band-pass filter and amplifier require a warm up period to reach a stable state after power-on so
any inputs should be ignored during this period.
In the AUTO mode within the first 10 seconds of power-on initialization, the system allows override control to access the
quickly install mode. However, after 40 seconds of the initial time the system allows override control between ON and AUTO.
It will remain in the warm up period if the total initial time has not elapsed after returning to AUTO.
In case that the ZC signal disappears more than 3 seconds, the chip will restart the initialization operation. However, the restart
initial time is always 40 seconds and cannot be extended by adding CRST to the RSTB pin as shown in Fig.5.
MODE: a tri-state input pin used to select the operating mode.
MODE

Description
VCC
Output always ON
RELAY outputs high at ZC rising edge
TRIAC outputs negative pulse train with synchronizing to ZC
GND
Output always OFF
RELAY outputs low
TRIAC outputs high
Open
AUTO
Outputs remain off state until activated by a valid PIR trigger signal. When working in
the AUTO mode, the chip allows override control by switching the ZC signal. MODE
outputs square wave with frequency of 31.25Hz.
ZC: a CMOS input structure. It receives AC line frequency and generates zero crossing pulses to synchronize the triac/relay
driver. With an effective ZC signal switching (switch OFF/ON 2 times within 3 seconds), the system provides the following
additional functions:
Quickly install mode: Within 10 seconds after power-on, effective ZC switching will force the chip to enter the quickly
install mode. During the mode, the outputs will be active for a duration of 1.3 seconds each time a valid PIR trigger signal
is received. If a time interval exceeds 32 seconds without a valid trigger input, the chip will enter the AUTO mode
automatically.

Override control: When the chip is working in the AUTO mode (MODE= open), the output is activated by a valid PIR trigger
signal and the active output duration is controlled by the OSCD oscillating period. The lamp can be switched always to “ON”
from the AUTO mode by either switching the MODE pin to VCC or switching the ZC signal by an OFF/ON operation of the
power switch (OFF/ON twice within 3 seconds). The term "override" refers to the change of operating mode by switching the
power switch. The chip can be toggled from ON to AUTO by an override operation. Shows as figure 7.
If the chip is overridden to ON and there is no further override operation, it will return to AUTO automatically after an
internal preset ON time duration has elapsed. This override ON time duration is set to 5 hours, refer to fig 7.
The PT8A2641/5/7 will flash on output pin when changing the operating mode. It will flash 3 times at a 1Hz rate each time
the chip changes from the AUTO mode to another mode or flash 3 times at a 2Hz rate when returning to the AUTO mode.
But
PT8A2642//6/8 does no flash at the same condition.
However, if the AUTO mode is changed by switching the MODE switch output will not flash.

Any operations during flash period are inactive, the flash period is about 3s from AUTO to ON, 3s from ON to AUTO.
COMPO: COMPO is output from comparator, it can be output at pin 10 if needed. Signal from two-stage opamp outputs to a
window comparator as pre-operation, COMPO outputs active positive pulses with various width once signal beyond window
level. Whether an active PIR signal is detected, see trigger timming diagram below for detail.

Note: 1. One measurable trigger width (Tmt) from comparator output is 24ms~ 32ms which varies with frequency of system
oscillator (typical system frequency=16KHz ).
2. The output is activated if the trigger signal conforms to the following criteria:
A trigger signal sustain duration:0.34 seconds.
2 trigger signals within 2 seconds with one of the trigger signal sustain:0.16 seconds.
More than 3 measurable triggers within 2 seconds.
3. The output duration is set by an external RC that is connected to the OSCD pin.
Retrigger
If another signal is attained in trigger hold time, the circuit will be retriggered, and the trigger hold time will be started from
this time.
