Typical Application Circuit Typical Application circuit of infrared remote control composed of IM50142P IC is showed as above.Picture:Typical Application Circuit of M50142P IC Notice:This circuit is the original picture of remote control infrared-emitter so the resistor sign hasn't been modified. Note:VT01and VT02 are direct coupling system drive circuits.Supply voltage reachs the groundafter it passesinfrared-emitting diode,VD01, and resistance, RO4, when VT02 tube short-circuits.At this time,infrared-emitting diode shines but without any information in infrared light so the remote control is invalid.
