TSOP12..SM1 Vishay Telefunken Photo Modules for PCM Remote Control Systems Available types for different carrier frequencies Type TSOP1230SM1 TSOP1236SM1 TSOP1238SM1 TSOP1256SM1 fo 30 kHz 36 kHz 38 kHz 56 kHz Type TSOP1233SM1 TSOP1237SM1 TSOP1240SM1 fo 33 kHz 36.7 kHz 40 kHz Description The TSOP12..SM1 – 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. GND VS OUT 94 8691 Features D Photo detector and preamplifier in one package D Internal filter for PCM frequency D Improved shielding against electrical field disturbance Special Features D Enhanced immunity against all kinds of disturbance light D No occurrence of disturbance pulses at the output D D D D TTL and CMOS compatibility Output active low Low power consumption Suitable burst length ≥10 cycles/burst Block Diagram 2 Input Control Circuit 80 kW 3 PIN AGC Band Pass Demodulator 1 GND 94 8136 VS OUT Document Number 82019 Rev. 7, 30-Mar-01 www.vishay.com 1 (7) TSOP12..SM1 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 3) (Pin 3) 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 (Pin 2) y Current ( ) Supply Voltage (Pin 2) Transmission Distance Output Voltage Low (Pin 3) Irradiance (30 – 40 kHz) Test Conditions VS = 5 V, Ev = 0 VS = 5 V, Ev = 40 klx, sunlight Ev = 0, test signal see fig.7, IR diode TSAL6200, IF = 400 mA IOSL = 0.5 mA,Ee = 0.7 mW/m2, f = fo, tp/T = 0.4 Pulse width tolerance: tpi – 5/fo < tpo < tpi + 6/fo, test signal see fig.7 Pulse width tolerance: tpi – 5/fo < tpo < tpi + 6/fo, test signal see fig.7 tpi – 5/fo < tpo < tpi + 6/fo Angle of half transmission distance Symbol ISD ISH VS d VOSL Ee min 0.35 Min 0.4 4.5 35 250 0.5 Typ 0.6 1.0 Max 1.5 5.5 Unit mA mA V m mV mW/m2 Irradiance (56 kHz) Ee min 0.4 0.6 mW/m2 Irradiance Directivity Ee max ϕ1/2 30 ±45 W/m2 deg Application Circuit 2 TSOP12..
