A The PIR sensor detects infrared power variations induced by the motion of a human body and converts it to voltage variations. This input voltage is fed into PT8A263 for signal processing. Bandpass filtering is first accomplished by a 2-stage op-amp, followed by the peak and valley voltages comparisons. If the input signal is larger than the specified peak voltage or smaller than the specified valley voltage for a certain period of time, this PIR trigger signal will be produced to the internal noise rejection circuit in which a valid trigger is qualified based on some criteria. The output signals will then be generated to drive external devices according to different mode of operations. Low Battery alarm indication can be given at LED pin when the division voltage is less than VEE/2. At the same time the system will be halt. Most of the internal circuits are hung up except oscillator and LED indication circuit. RST RST is 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 RST pin is an open circuit (without CRST), the initial time is the default (40 seconds). VEE VEE supplies power to the analog front-end circuit with a stabilized voltage that is 3.6V with respect to GND normally. Power On Initial The PIR signal amplifier requires a warm up period after power-on. The input should be disabled during this period. OSC OSC is an I/O pin of internal oscillator. System frequency of 16KHz can be generated when connected to an external RC. Operational Mode The operation modes of PT8A263 are shown in the following table. Mode of Operation/2 SEL1 SEL2 Functions Normal Alarm: OUT1 = low (active) for 5 seconds after the first trigger. OUT2 goes low for 5 seconds after the 2nd trigger. LED does not latch trigger status. OUT2 (low active) will not trigger if there is no PIR signal 12 1 1 seconds after the first trigger. Normal Alarm with Delay: OUT1 goes low after first triggered, if the second trigger signal comes after 15 seconds, OUT2 keep high, if the second trigger signal comes after 12 seconds but less than 15 seconds, OUT2 0 1 will goes low for 5 seconds. LED is latched on until power down or reset the chip. Siren Alarm: Complimentary drive high pitch piezo buzzer. Center frequency = 1kHz (options for 500Hz and 2kHz). 2 stages of alarm: First trigger: Output is 1/4 sec on, 4 sec off. If no 2nd trigger within 12 sec, all outputs are 1 0 reset, no sound. 2nd trigger: Output is 1/4 sec on, 2 sec off for 30 sec. After 30 sec, output = 1 sec on, 1/2 sec off, continue for 5 minutes. After that, the chip enters stop mode. LED is latched on after 2nd trigger, until power down or chip reset. Door Chime mode: Once trigger occurs, OUT1 is active (high) for 1 sec, OUT2 is active (high) for another 1 0 0 sec after OUT1 is asserted. LED has no latch function. 12-07-0006 PT0084-6 6 07/06/12/12 PT8A263 PIR Alarm Controller ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| Timing Diagram PIR Signal Trigger and Output Signals for Door Chime Mode RST TRI_EN 40s w arm-up time Comparator input <32ms Comparator output >32ms >160ms <2s (1) >288ms (2) (3) Valid trigger SEL2,SEL1 00 00 = Door Chime mode 00 OUT1 1s OUT2 00 1s 1s LED 125Hz pulse Notes: The PIR trigger signal is qualified to be a valid PIR trigger signal if it conforms to one of the following criteria : 1.
