It can operate with a 2wire 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. · · · · Operating voltage: 5V (Typ.) Average supply current: 120µ (Typ.) A 2 stage op-amp for filter. Build-in noise rejection circuit. On-chip regulator. Adjustable output duration Override function. ON/AUTO/OFF selectable by MODE pin Apply to AC 220V/50Hz and 110V/60Hz. Auto-reset if the ZC signal disappears over 3 seconds Output pulse (PT8A2641/5/7 PT8A2641/5/7) to drive triac or output level (PT8A2642/6/8 PT8A2642/6/8) to drive relay. CDS to enable/disable output. 40 second warm-up. Quick check mode for installation. 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 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.

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). OSCD: input pin of timing oscillator. It' connected to an external RC to obtain the desired output timer. Variable output turns 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 PT8A2642/6/8, or as a TRIAC driving (active low) output for the PT8A2641/5/ 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. CDS LOW HIGH Status Day Time Night CDSO inactive active Figure 4 CDS input interface and enable debounce RW CDS Photo Resistor CDS CDS CDSO enable 5s disable 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). enable Figure 5 RSTB application example VC C RES T RST B CRST VSS PT0192 PT0192(08/05) Ver:2 4 Data Sheet PT8A2641-2642/2645-2648 PT8A2641-2642/2645-2648 PIR Sensor Light Switch PT Pericom Technology Inc. ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| 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 VCC Operating Mode Output always ON GND Output always OFF Open AUTO Description RELAY outputs high at ZC rising edge TRIAC outputs negative pulse train with synchronizing to ZC RELAY outputs low TRIAC outputs high 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 withou t a valid trigger input, the chip will enter the AUTO mode automatically. Figure 6 Test mode 10s RSTB 40s warm up time Test enable ZC 0.34s Relay (Triac) * OFF * ON 1.3s 2s ON 1.3s ON 1.3s 2s ON 1.3s >32s *&*:flash times at 2 rate for 2641/5/7;for 2642/6/8,No *&*:flash 33 times at2HzHz rate for 2641;for 2642,No flash flash 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 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 PT8A2642//6/8 does no flash at the same condition.

Fig.7 ZC override timing 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. Trigger timing Figure 8 Trigger timing Note: 1. One measurable trigger width () 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: q A trigger signal sustain duration:0.34 seconds. q 2 trigger signals within 2 seconds with one of the trigger signal sustain:0.16 seconds. q 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.
