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. 16 081 Features D Photo detector and preamplifier in one package D Internal filter for PCM frequency D Improved shielding against electrical field disturbance D TTL and CMOS compatibility D Output active low D D D D Low power consumption High immunity against ambient light Enhanced data rate of 2400 bit/s Operation with short bursts possible (≥6 cycles/burst) Block Diagram 2 Control Circuit Input 30 kW 1 PIN AGC Band Pass VS OUT Demodulator 3 GND 14318 Document Number 82123 Rev. 5, 30-Mar-01 www.vishay.com 1 (8) TSOP21..UH1 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 2) (Pin 2) (Pin 1) (Pin 1) Symbol VS IS VO IO Tj Tstg Tamb Ptot Tsd x (Tamb 85 °C) t 10 s, 1 mm from case x 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 Typ 1.1 1.4 Unit mA mA V m Basic Characteristics Tamb = 25_C Parameter Supply y Current ((Pin 2)) Supply Voltage (Pin 2) Transmission Distance Output Voltage Low (Pin 1) Irradiance (30 – 40 kHz) Irradiance (56 kHz) Irradiance Directivity Test Conditions VS = 5 V, Ev = 0 VS = 5 V, Ev = 40 klx, sunlight Symbol ISD ISH VS d Ev = 0, test signal see fig.8, IR diode TSAL6200, IF = 250 mA IOL = 0.5 mA,Ee = 0.7 mW/m2, f = fo Pulse width tolerance: tpi – 5/fo < tpo < tpi + 5/fo, test signal see fig.8 4.5 Max 1.5 5.5 35 VOL Ee min 0.2 250 0.4 mV mW/m2 Ee min 0.3 0.5 mW/m2 Ee max ϕ1/2 Angle of half transmission distance Min 0.8 W/m2 deg 30 ±45 Application Circuit 100 W *) 2 TSOP21..UH1 TSAL62.. 1 4.7 mF *) +5V >10 kW optional **) mC 3 16207 GND *) recommended to suppress power supply disturbances **) The output voltage should not be hold continuously at a voltage below 3.3V by the external circuit. www.vishay.com 2 (8) Document Number 82123 Rev. 5, 30-Mar-01 TSOP21..UH1 Vishay Telefunken Suitable Data Format The circuit of the TSOP21..UH1 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 and disturbance signal are carrier frequency, burst length and duty cycle. The data signal should fullfill the following condition: • Carrier frequency should be close to center frequency of the bandpass (e.g. 38kHz). • After each burst which is between 6 cycles and 70 cycles a gap time of at least 10 cycles is neccessary. • For each burst which is longer than 1.8ms a corresponding gap time is necessary at some time in the data stream. This gap time should have at least same length as the burst. • Up to 2200 short bursts per second can be received continuously. 5 When a disturbance signal is applied to the TSOP21..UH1 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 TSOP21..UH1 are: • Burst length should be 6 cycles/burst or longer. 0 Some examples for suitable data format are: NEC Code, Toshiba Micom Format, Sharp Code, RC5 Code, RC6 Code, RCMM Code, R–2000 Code, RECS–80 Code. • DC light (e.g. from tungsten bulb or sunlight) • Continuous signal at 38kHz or at any other frequency • Signals from fluorescent lamps with electronic ballast (an example of the signal modulation is shown in the figure below). 10 15 20 time [ms] IR Signal from Fluorescent Lamp with low Modulation Document Number 82123 Rev. 5, 30-Mar-01 www.vishay.com 3 (8) TSOP21..UH1 Vishay Telefunken Typical Characteristics (Tamb = 25_C unless otherwise specified) Ee min – Threshold Irradiance ( mW/m2 ) /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.
