They can operate in 2-wire configuration for triac applications or in 3-wire configuration for relay applications. OSCS is a system oscillator I/O pin connected to an external RC to generate system frequency of 16kHz. OSCD is an output timing oscillator I/O pin. It抯 connected to an external RC to obtain the desired turn-on duration by selecting various values of RC or using a variable resistor.FOSCD is the frequency of OSCD pin, output timing can be caculated as the formula: TD = 21504/FOSCD The PIR sensor detects infrared power variations caused by motion of a human body and transfer to a voltage variation. If the PIR output voltage variation conforms to criteria, the lamp is turned on for an adjustable duration. The PT8A2611 (or 2621) offers three operating modes (ON, AUTO, OFF) which can be set through a MODE pin. When the device is working in AUTO mode, the user can override the mode to switch it to TEST mode or manual ON mode, or return to the AUTO mode by switching power switch. CDS Input Circuit CDS is a CMOS schmitt trigger input pin. It is used to distinguish between day time and night time. When the input voltage of CDS is high the PIR input is enabled, when CDS low the PIR input disabled. The input disable-to-enable debounce time is 5 seconds. Connect this pin to VCC when not using it. The CDS input is ignored by PT8A2611when the TRIAC output is active, however, PT8A2621抯 CDS can not be ignored anytime. Figure 1. System Oscillator Figure 2.

MODE is a tri-state input pin for operation mode selection. See the following table 2. 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 (8 hours). Note:Flash is only for the TRIAC Rev. Override Control (for PT8A2621 only): The term override refers 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 controlled by the OSCD oscillation period. The lamp can be switched to ON from the AUTO mode by either switching the MODE pin to VCC or switching the power switch twice within 3 seconds. RST Pin RST is used to reset the device. It is internal pull-high and active low. The use of CRST can extend the power-on initial time. If the RST pin is openned (without CRST), the initial time is 40 seconds. See Figure 6. Table 2. Operation Modes by MODE Pin MODE Status Operation Mode Description VCC 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. Figure 5.

However, the restart initial time is always 40 seconds and cannot be extended by adding CRST to the RST pin as shown in Figure 4. Power On Initial The PIR signal amplifier requires a warm up period after poweron. The input should be disabled during this period. Trigger In the AUTO mode within the first 40 seconds of the initial time the chip allows override control to enter the quickly install mode, After 40s of the initial time the chip 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. The trigger timing is shown in Figure 7. 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. Figure 7.

The output is activated if the trigger signal conforms to the following criteria: - More than 3 triggers within 2 seconds, - A trigger signal sustain duration > 0.34 seconds, and - 2 triggers within 2 seconds with pulse duration of one > 0.16 seconds. -The effective comparator output width is 24ms.(Fosc=16KHz) 2. The output duration is set by an external RC connected to the OSCD pin.
