Logic control circuit Logic control circuit mainly carries out logic control function. It not only collects signals from other blocks, but also generates various driving signals including RELAY&DISC. Besides, an external LED will flash at about 1Hz and a buzzer will make a sound with a frequency of 4KHz every 0.5s for 6 times or continual after internal timer times out. Signals at RELAY will control external relay to decide whether IRON heats or not. Sensor signal processor The core in the whole system is how to correctly detect the position and movement of sensor so that the system can be always under safe control. Thus, it is critical to accurately and correctly deal with signal from sensor in different status and eliminate the noise caused by debounce action from sensor. Here, a unique structure is used to do the high-requirement signal processing. In real application of IRON, sensor needs to be installed according to certain requirements (for example its inclination). Timer Timer block mainly generates various timing signal according to the position of IRON. It is easy to get accurate timer (30s/8min/10min/15min) by using AC 60Hz/50Hz signal as timing reference. As above description, Iron in Horizontal position over 30s will stop heating. While Iron in vertical position over 8min/10min/ 15min will also stop heating. Buzzer A buzzer will make 0.5S sound with a frequency of 4 KHz for 6 times or continual after internal timer timeouts. LED Whenever power on or heating, LED pin is floating and an external LED will turn on. After times out, LED pin outputs pulse and an external LED will flash at about 1Hz. 12-07-0006 PT0336-1 3 07/06/12 PT8A3514/15/16/17/18/19(C/D) Smart Iron Controller ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| |||||||||||||||| Application Circuit Note: Suggest the parameters of relay meet the following specification: 24VDC, 1.6KΩ Coil resistance R1 R2 12K 15K 240VAC R4 D1 100K 1N4007 R3 10K O UT C3 104 C2 22uF/16V D2 1N4148 J1 RELAY 2N5551 Q2 2N5551 Q1 C1 10uF/100V R5 100K R6 1M IC1 1 DISC/BUZ 2 RELAY 3 LED ACCLK LED 4 240VAC VCC SW GND TEST PT8A351x 8 7 6 C4 103 5 R7 51.K SENSOR Figure 1 Typical Application Circuit of PT8A351XC 240V Figure 5 Typical Application Circuit of PT8A351x 240V/50Hz D1 120VAC 1N4007 R1 R3 6.8K OUT C3 104 C2 R2 10K 22uF/16V D2 1N4148 J1 RELAY C1 10uF/100V VCC 100K 2N5551 Q2 2N5551 Q1 R6 100K R5 510K IC1 1 2 3 4 LED DISC/BUZ RELAY LED GND VCC ACCLK SW TEST 8 7 6 5 C4 103 R7 51K PT8A351x 120VAC SENSOR Figure 2 Typical Application Circuit of PT8A351XD 120V Figure 6 Typical Application Circuit of PT8A351x 120V/60Hz 12-07-0006 PT0336-1 4 07/06/12 PT8A3514/15/16/17/18/19(C/D) Smart Iron Controller ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| |||||||||||||||| D1 240VAC 1N4007 R1 R2 12K 15K D2 BUZ R3* 1.8K Infrared LED D2 1N4148 R5 100K 20mm R4* 8.2K O UT J1 RELAY C3 104 C1 C2 10uF/100V 2N5551 Q1 R7 1M 22uF/16V 2N5551 Q2 R6 51K IC1 1 2 3 4 LED DISC/BUZ RELAY VCC ACCLK LED SW GND TEST 8 7 6 C4 D3 5 103 PT8A351x R8 51K Photo Diode 240VAC Figure 3 Typical Application Circuit of PT8A351XC 240V Figure 7 Typical Application Circuit of PT8A351x 240V 50Hz R1 6.8K 120VAC D1 D2 1N4007 BUZ R2* 1.8K Infrared LED D2 1N4148 O UT R4 100K 20mm VCC R3* 8.2K J1 RELAY C3 104 C1 C2 22uF/16V 2N5551 Q2 10uF/100V 2N5551 Q1 R5 51K R6 510K IC1 1 2 3 4 LED DISC/BUZ RELAY LED GND VCC ACCLK SW TEST 8 7 6 5 D3 103 PT8A351x 120VAC C4 R8 51K Photo Diode Figure 4 Typical Application CircuitofofPT8A351x PT8A351XD 120V Figure 8 Typical Application Circuit 120V 60Hz 12-07-0006 PT0336-1 5 07/06/12 |||||||||||||||| PT8A3514/15/16/17/18/19(C/D) Smart Iron Controller ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| Mechanical Information PE (DIP-8) Symbol A A1 A2 B B1 c D E E1 e L E2 Note: 1) Controlling dimensions in millimeters. 2) Ref : JEDEC MS-001D/BA 12-07-0006 Dimensions In Millimeters Min Max 3.710 4.310 0.510 3.200 3.600 0.380 0.570 1.524 BSC 0.204 0.360 9.000 9.400 6.200 6.600 7.320 7.920 2.540 BSC 3.000 3.600 8.400 9.000 PT0336-1 6 07/06/12 |||||||||||||||| PT8A3514/15/16/17/18/19(C/D) Smart Iron Controller ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| WE (SOIC-8) Symbol A A1 A2 b c D E E1 e L θ Note: 1) Controlling dimensions in millimeters. 2) Ref : JEDEC MS-012E/AA 12-07-0006 Dimensions In Millimeters Min Max 1.350 1.750 0.100 0.250 1.350 1.550 0.330 0.510 0.170 0.250 4.700 5.100 3.800 4.000 5.800 6.200 1.27 BSC 0.400 1.270 0° 8° PT0336-1 7 07/06/12 PT8A3514/15/16/17/18/19(C/D) Smart Iron Controller ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| |||||||||||||||| Ordering Information Part Number Package Code Package PT8A351xCPE P Lead free DIP-8 PT8A351xCPE P Lead free DIP-8 PT8A351xDWE W Lead free and Green SOIC-8 PT8A351xDWE W Lead free and Green SOIC-8 Note:  “x” shows different function.
