VSS OFF Output is always OFF: RELAY outputs low for relay driving. TRIAC outputs high for triac driving. AUTO Outputs remain in the off state until activated by a valid PIR input trigger signal. When working in the AUTO mode, the chip allows override control by switching the ZC signal. Output Timing Oscillator RELAY (TRIAC) RELAY is an output pin set as a RELAY driving (active high) output for the HT7610A/11A, or as a TRIAC driving (active low) output for the HT7610B/11B. The output active duration is controlled by the OSCD oscillating period. HT7610A/11A HT7610B/11B RELAY TRIAC OUTPUT Description Open CDS CDS is a CMOS Schmitt Trigger input structure. It is used to distinguish between day time and night time. When the input voltage of CDS is high the PIR input is enabled. On the other hand, when CDS is low the PIR input is disabled.

It receives AC line frequency and generates zero crossing pulses to synchronize the triac driver. By effective ZC signal switching (switch OFF/ON 1 or 2 times within 3 seconds by mask option), the chip provides the following additional functions: V V C C D D R E S T 1 0 0 m F R S T C R S T · Test mode control V E E Within 10 seconds after power-on, effective ZC switching will force the chip to enter the test mode. During the test mode, the outputs will be active for a duration of 2 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 automatically enter the AUTO mode. Fig.1 RST Application Example Power-on Initial The PIR signal amplifier requires a warm up period after power-on. The input should be disabled during this period. · Override control In the AUTO mode within the first 10 seconds of power-on initialization, the chip allows override control to enter the test mode. After 40 seconds 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. When the chip is working in an AUTO mode (MODE=open), the output is activated by a valid PIR trigger signal and the output active duration is controlled by an OSCD oscillating period. The lamp can be switched always to ²ON² from the AUTO mode by either switching the MODE pin to VDD or switching the ZC signal by an OFF/ON operation of the power switch (OFF/ON once or twice within 3 seconds by mask option). The term ²override² 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. If the chip is overridden to ON and there is no further override operation, it will automatically return to AUTO after an internal preset ON time duration has elapsed. This override ON time duration is 8 hours. The chip provides a mask option to determine the output flash times (3 times) when changing the operating mode. It will flash 3 times at a 1Hz rate each time the chip changes from an AUTO mode to another mode or flash 3 times at a 2Hz rate when returning to the AUTO mode. But if the AUTO mode is changed by switching the MODE switch it will not flash. In case that the ZC signal disappears for 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 RST pin as shown in the Fig.1. Mask Options The HT761x offers mask options to select the output flash (3 times) when changing the operating mode. The chip will flash 3 times at a 1Hz rate each time it changes from AUTO to another mode and flash 3 times at a 2Hz rate when it returns to the AUTO mode. However the chip will not flash if the mode is changed by switching the MODE switch. · Options for effective override: Once or twice Off/On op- eration of power switch within 3 seconds. Once for HT7611A/HT7611B and twice for HT7610A/HT7610B. · Options for output flash to indicate effective override operation. Flash for HT7610A/HT7610B and no flash for HT7611A/HT7611B. 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 secs).

Usually the second stage PIR amplifier is a simple capacitively coupled inverting amplifier with a low pass configuration. The noninverting input terminal is biased to the center point of the comparator window and the output of the second stage amplifier is directly coupled to the comparator center point. In the Fig.2 below there are 2 op-amps with different applications. OP1 can be used independently as a first stage inverting or non-inverting amplifier for the PIR. As the output of OP2 is directly connected to the input of the comparator, it is used as a second stage amplifying device. The non-inverting input of OP2 is connected to the comparator¢s window center point and can be used to check this voltage and to provide a bias voltage that is equal to the center point voltage of the comparator. In 1 Fig.2 the window level of the comparator is set to 16 (VDD-VEE). V In Fig.3 OP2P is directly connected to the comparator window center, and with the C3 filter it can act as the R2 bias for OP2. For this configuration AV = , low cutoff R1 1 frequency fL= , high cutoff frequency 2 p R1C1 1 f H= . By changing the value of R2 the sensitiv2 pR2C2 ity can be varied. C1 and C3 should be of low leakage types to prevent the DC operating point from changing due to current leakage.
