1 IR Receiver Modules for Remoe Conrol Sysems Descripion The HS38B3VM is a miniaurized receiver for infrared remoe conrol sysems. A PIN diode and a preamplifier are assembled on a lead frame, he epoxy package acs as an IR filer. The demodulaed oupu signal can be direcly decoded by a microprocessor. The HS38B3VM is compaible wih all common IR remoe conrol daa formas. This componen has no been qualified according o auomoive specificaions. 926 Feaures Very low supply curren Phoo deecor and preamplifier in one package e3 Inernal filer for PCM frequency Improved shielding agains EMI Supply volage: 2.5 V o 5.5 V Improved immuniy agains ambien ligh Componen in accordance o RoHS 22/95/EC and WEEE 22/96/EC Insensiive o supply volage ripple and noise Block Diagram Mechanical Daa Pinning: = OUT, 2 = GND, 3 = V S Applicaion Circui 6833 Inpu AGC Band Pass 3 kω Demodulaor 3 V S OUT 9267_8 IR Transmier wih TSALxxxx HS38B3VM Circui V S OUT µc 2 V O PIN Conrol Circui GND GND No exernal componens are required Documen Number 8769 Rev.., 4-Sep-7

5 Suiable Daa Forma The HS38B3VM is designed o suppress spurious oupu pulses due o noise or disurbance signals. Daa and disurbance signals can be disinguished by he devices according o carrier frequency, burs lengh and envelope duy cycle. The daa signal should be close o he band-pass cener frequency (e.g. 38 khz) and fulfill he condiions in he able below. When a daa signal is applied o he HS38B3VM in he presence of a disurbance signal, he sensiiviy of he receiver is reduced o insure ha no spurious pulses are presen a he oupu. Some examples of disurbance signals which are suppressed are: DC ligh (e.g. from ungsen bulb or sunligh) Coninuous signals a any frequency Srongly or weakly modulaed noise from fluorescen lamps wih elecronic ballass (see figure 5 or figure 6).

Regularly and coninuously improve he performance of our producs, processes, disribuion and operaing sysems wih respec o heir impac on he healh and safey of our employees and he public, as well as heir impac on he environmen. I is paricular concern o conrol or eliminae releases of hose subsances ino he amosphere which are known as ozone depleing subsances (ODSs). The Monreal Proocol (987) and is London Amendmens (99) inend o severely resric he use of ODSs and forbid heir use wihin he nex en years. Various naional and inernaional iniiaives are pressing for an earlier ban on hese subsances. Vishay Semiconducor GmbH has been able o use is policy of coninuous improvemens o eliminae he use of ODSs lised in he following documens.. Annex A, B and lis of ransiional subsances of he Monreal Proocol and he London Amendmens respecively 2. Class I and II ozone depleing subsances in he Clean Air Ac Amendmens of 99 by he Environmenal Proecion Agency (EPA) in he USA 3. Council Decision 88/54/EEC and 9/69/EEC Annex A, B and C (ransiional subsances) respecively. Vishay Semiconducor GmbH can cerify ha our semiconducors are no manufacured wih ozone depleing subsances and do no conain such subsances. We reserve he righ o make changes o improve echnical design and may do so wihou furher noice. Parameers can vary in differen applicaions. All operaing parameers mus be validaed for each cusomer applicaion by he cusomer. Should he buyer use producs for any uninended or unauhorized applicaion, he buyer shall indemnify agains all claims, coss, damages, and expenses, arising ou of, direcly or indirecly, any claim of personal damage, injury or deah associaed wih such uninended or unauhorized use.
