Sheet No.: OP06013 3 GP1UX31QS Series ■ Precautions for Operation 1. When this infrared remote control detecting unit shall be adopted for wireless remote control, please use the following signal format .  (NEC code,RC-6code etc.) n ・Total duty ratio Dt (Emitting time  t Σ N / Transmitting time for 1 block T) : 40% or less. N=1 ・ON signal time and OFF signal time Supply Voltage Vcc ON signal time per 1bit tON OFF signal time per 1bit tOFF 2.7 to 3.0V 3.0 to 5.5V 200μs or more 400μs or more 300μs or more Transmitting time for 1 block:T TON t1 t2 t3 tn n Dt =(Σ tN /T)×100 (%) N=1 In case the signal format of total duty and/or ON/OFF signal time dosen`t meet the conditions noted above, there is a case that reception distance much reduces or output dose not appear. 2. Use the light emitting unit (remote control transmitter), in consideration of performance, characteristics, operating conditions of light emitting device and the characteristics of the light detecting unit. 3. Pay attention to a malfunction of the light detecting unit when the surface is stained with dust and refuse. Care must be taken not to touch the light detector surface. If it should be dirty, wipe off such dust and refuse with soft cloth so as to prevent scratch. In case some solvents are required, use methyl alcohol, ethyl alcohol or isopropyl alcohol only. Also, protect the light detecting unit against flux and others, since their deposition on the unit inside causes reduction of the function, fading of markings such as the part number. 4. Unnecessary force shoud not be applied to terminal. 5. Do not push the light detector surface (photodiode) from outside. 6. To avoid the electrostatic breakdown of IC, handle the unit under the condition of grounding with human body, soldering iron, etc. 7. Since conductive thermo plasticity is used in 2nd mold regin,please be careful not to come in contact with PCB land pattern. 8. External Circuit Examples (Mount the outer parts as near the unit as possible). GND VCC CO + GND R1 Ve VOUT VO (Circuit parameters) R1=47Ω±5% C1=47μF In setting R1 and C1, use suitable values after considering under the real condition The circuit constant is a example. It is difference from mounting equipment. Please select it by your mounting equipment. This device has a transistor as protection element between VCC and GND to improve anti-static electricity proof. Please be carefully not to apply exceeding the absolute maximum ratings of applying voltage and continuous high voltage spike noise because there is cases that transistor will be short by secondary breakdown generally. In order to do difficultly, Please add CR filter(47Ω(1/10W), 10μF or more)such as external circuit example above near VCC. Sheet No.: OP06013 4 GP1UX31QS Series 9. There is a possibility that noise on output may be caused by environmental condition (Disturbing light noise, Electromagnetic noise, Power supply line noise, etc.) even if there is no input transmission signal. 10. Please shall confirm operation or your actual machine. Because the output pulse width of this product is fluctuated by environmental conditions such as signal format, temperature, distance from transmitter, and so on. 11. In case that this product is kept in high humidity condition, it may be hard to solder, please be careful enough about storage method. Depend on the flux you select, there are different solderabilities, so please select a suitable flux and use it. 12. This product dose`t correspond to soldering by reflow. 13. Please make sure in case pf hand soldering that yue the solder iron with less than 45W power and solder iron point(edge) temperature is less than 320℃ within 3 seconds,and also don't add any force to lead frame directly.And please make sure never to touch 2nd mold resin by a solding. 14. When using this device,please be careful not to cause dew drop. Be aware that the dew drop rusts lead pins portion and others, may affect the electric characteristics. 15. The lead flame may be deformed since the device is packed in vinyl bag. Sheet No.: OP06013 5
