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. 96 12582 Features D D D D D Photo detector and preamplifier in one package Internal filter for PCM frequency TTL and CMOS compatibility Output active low Improved shielding against electrical field disturbance Special Features D Small size package D Supply voltage 3–6 Volt D Enhanced immunity against all kinds of disturbance light D No occurrence of disturbance pulses at D Short settling time after power on (<200ms) the output D Suitable burst length ≥6 cycles/burst Block Diagram 3 Input Control Circuit 80 kW 1 PIN AGC Band Pass Demodulator 2 GND OUT VS 16249 Document Number 82133 Rev. 2, 13-Jun-00 www.vishay.de • FaxBack +1-408-970-5600 1 (7) TSOP18..SS3VA 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 85 °C) t 10 s, 1 mm from case x x Basic Characteristics Tamb = 25_C Parameter Supply y Current ( (Pin 3) ) Supply Voltage (Pin 3) Transmission Distance Test Conditions VS = 3 V, Ev = 0 VS = 3 V, Ev = 40 klx, sunlight Symbol ISD ISH VS d VOSL Ee min Ee min Ee max ϕ1/2 30 ±45 Min 0.5 3.0 35 250 0.5 0.7 Typ 0.8 1.0 Max 1.1 6.0 Unit mA mA V m mV mW/m2 mW/m2 W/m2 deg Ev = 0, test signal see fig.6, IR diode TSAL6200, IF = 300 mA Output Voltage Low (Pin 1) IOSL = 0.5 mA,Ee = 0.7 mW/m2, f = fo Irradiance (30 – 40 kHz) Pulse width tolerance: tpi – 4/fo < tpo < tpi + 5/fo, test signal see fig.6 Irradiance (56 kHz) Pulse width tolerance: tpi – 4/fo < tpo < tpi + 5/fo, test signal see fig.6 Irradiance Directivity Angle of half transmission distance 0.3 0.4 Application Circuit 330 W *) >10 k recomm. +VS 3 TSOP18..SS3VA TSAL62.. 4.7 F *) m W 1 mC 2 GND 15803 *) recommended to suppress power supply disturbance www.vishay.de • FaxBack +1-408-970-5600 2 (7) Document Number 82133 Rev. 2, 13-Jun-00 TSOP18..SS3VA Vishay Telefunken Suitable Data Format The circuit of the TSOP18..SS3VA 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 25ms) at least each 150ms (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..SS3VA 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..SS3VA 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 20 40 60 time [ms] 80 100 120 140 Figure A: Data Signal (Output of IR Receiver) with a Signal Gap Time of 45ms 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 (suppressed by TSOP18..SS3V) Document Number 82133 Rev. 2, 13-Jun-00 www.vishay.de • FaxBack +1-408-970-5600 3 (7) TSOP18..SS3VA Vishay Telefunken Typical Characteristics (Tamb = 25_C unless otherwise specified) 1.0 0.8 E e min – Threshold Irradiance (mW/m2 ) /eE – Rel.
