| TSOP18..ON1 Vishay Telefunken Photo Modules for PCM Remote Control Systems Available types for different carrier frequencies Type TSOP1830ON1 TSOP1836ON1 TSOP1838ON1 TSOP1856ON1 fo 30 kHz 36 kHz 38 kHz 56 kHz Type TSOP1833ON1 TSOP1837ON1 TSOP1840ON1 fo 33 kHz 36.7 kHz 40 kHz Description The TSOP18..ON1 - series are miniaturized receivers for infrared remote control systems. PIN diode and preamplifier are assembled on lead frame, the epoxy package is designed as IR filter. The demodulated output signal can directly be decoded by a microprocessor. The main benefit is the reliable function even in disturbed ambient and the protection against uncontrolled output pulses. 16115 Features D Photo detector and preamplifier in one package D Internal filter for PCM frequency D TTL and CMOS compatibility D Output active low D Improved shielding against electrical field disturbance D Suitable burst length 6 cycles/burst Special Features D Small size package D Enhanced immunity against all kinds of disturbance light D No occurrence of disturbance pulses at the output D Short settling time after power on (<200ms) Block Diagram 3 Input Control Circuit VS 30 kW 1 OUT PIN AGC Band Pass Demodulator 2 9612226 GND Document Number 82080 Rev. 6, 23-Feb-01 www.vishay.com 1 (7) TSOP18..ON1 Vishay Telefunken Absolute Maximum Ratings Tamb = 25_C Parameter Supply Voltage Supply Current Output Voltage Output Current Junction Temperature Storage Temperature Range Operating Temperature Range Power Consumption Soldering Temperature Test Conditions (Pin 3) (Pin 3) (Pin 1) (Pin 1) Symbol VS IS VO IO Tj Tstg Tamb Ptot Tsd Value -0.3...6.0 5 -0.3...6.0 5 100 -25...+85 -25...+85 50 260 Unit V mA V mA C C C mW C (Tamb x 85 C) t x 10 s, 1 mm from case Basic Characteristics Tamb = 25_C Parameter Su ly Supply Current (Pin 3) Supply Voltage (Pin 3) Transmission Distance Output Voltage Low (Pin 1) Irradiance (30 - 40 kHz) Test Conditions VS = 5 V, Ev = 0 VS = 5 V, Ev = 40 klx, sunlight Ev = 0, test signal see fig.6, IR diode TSAL6200, IF = 300 mA IOSL = 0.5 mA, Ee = 0.7 mW/m2, f = fo Pulse width tolerance: tpi - 4/fo < tpo < tpi + 6/fo, test signal see fig.6 Pulse width tolerance: tpi - 5/fo < tpo < tpi + 5/fo, test signal see fig.6 Angle of half transmission distance Symbol ISD ISH VS d VOSL Ee min 0.3 Min 0.9 4.5 35 250 0.5 Typ 1.2 1.3 Max 1.5 5.5 Unit mA mA V m mV mW/m 2 Irradiance (56 kHz) Ee min 0.4 0.7 mW/m 2 Irradiance Directivity Ee max 1/2 30 45 W/m 2 deg Application Circuit 100 W *) +5V >10 kW 3 TSOP18..ON1 TSAL62.. 4.7 mF *) optional 1 mC 2 GND 15905 *) recommended to suppress power supply disturbances www.vishay.com 2 (7) Document Number 82080 Rev. 6, 23-Feb-01 TSOP18..ON1 Vishay Telefunken Suitable Data Format The circuit of the TSOP18..ON1 is designed in that way that unexpected output pulses due to noise or disturbance signals are avoided. A bandpassfilter, an integrator stage and an automatic gain control are used to suppress such disturbances. The distinguishing mark between data signal ( not suppressed) and disturbance signal (supressed) are carrier frequency, burst length and Signal Gap Time (see diagram below). The data signal should fullfill the following condition: * Carrier frequency should be close to center frequency of the bandpass (e.g. 38kHz). * Burst length should be 6 cycles/burst or longer. * After each burst a gap time of at least 9 cycles is neccessary. * The data format should not make a continuous signal transmission. There must be a Signal Gap Time (longer than 15ms) at least each 90ms (see Figure A). Some examples for suitable data format are: NEC Code (repetitive pulse), NEC Code (repetitive data), Toshiba Micom Format, Sharp Code, RC5 Code, RECS-80 Code, R-2000 Code. When a disturbance signal is applied to the TSOP18..ON1 it can still receive the data signal. However the sensitivity is reduced to that level that no unexpected pulses will occure. Some examples for such disturbance signals which are suppressed by the TSOP18..ON1 are: * DC light (e.g. from tungsten bulb or sunlight), * Continuous signal at 38kHz or at any other frequency, * Signals from fluorescent lamps (see Figure B). * Continuous IR signal (e.g. 1ms burst, 2ms pause) Signal Gap Time 0 10 20 30 40 50 time [ms] 60 70 80 90 100 Figure A: Data Signal (Output of IR Receiver) with a Signal Gap Time of 20ms Signal Gap Time 0 2 4 6 8 10 time [ms] 12 14 16 18 20 Figure B: Disturbance Signal from Fluorescent Lamp with Signal Gap Time of 7ms Document Number 82080 Rev. 6, 23-Feb-01 www.vishay.com 3 (7) TSOP18..ON1 Vishay Telefunken Typical Characteristics (Tamb = 25_C unless otherwise specified) 1.0 /eE - Rel.

Meet all present and future national and international statutory requirements. 2. Regularly and continuously improve the performance of our products, processes, distribution and operating systems with respect to their impact on the health and safety of our employees and the public, as well as their impact on the environment. It is particular concern to control or eliminate releases of those substances into the atmosphere which are known as ozone depleting substances (ODSs). The Montreal Protocol (1987) and its London Amendments (1990) intend to severely restrict the use of ODSs and forbid their use within the next ten years. Various national and international initiatives are pressing for an earlier ban on these substances. Vishay Semiconductor GmbH has been able to use its policy of continuous improvements to eliminate the use of ODSs listed in the following documents. 1. Annex A, B and list of transitional substances of the Montreal Protocol and the London Amendments respectively 2. Class I and II ozone depleting substances in the Clean Air Act Amendments of 1990 by the Environmental Protection Agency (EPA) in the USA 3. Council Decision 88/540/EEC and 91/690/EEC Annex A, B and C (transitional substances) respectively. Vishay Semiconductor GmbH can certify that our semiconductors are not manufactured with ozone depleting substances and do not contain such substances. We reserve the right to make changes to improve technical design and may do so without further notice. Parameters can vary in different applications. All operating parameters must be validated for each customer application by the customer. Should the buyer use Vishay-Telefunken products for any unintended or unauthorized application, the buyer shall indemnify Vishay-Telefunken against all claims, costs, damages, and expenses, arising out of, directly or indirectly, any claim of personal damage, injury or death associated with such unintended or unauthorized use.
