4. Output Phototransistor: The output side has a phototransistor that is controlled by the light from the LED, allowing the transfer of signals.
5. Current Transfer Ratio (CTR): The typical CTR ranges between 50% and 600%, indicating the efficiency of signal transfer from input to output.
6. Operating Temperature: It supports a wide operating temperature range from -55°C to 110°C.
7. Low Input Current: Requires a low input current, making it energy-efficient.
8. Applications: Commonly used in applications like power supply feedback circuits, microcontroller interfaces, and signal isolation.
These features make the TLP292 suitable for various applications requiring reliable electrical isolation and signal transmission.
Pinout
1. Pin 1 (Anode): This pin is connected to the anode of the infrared LED. It should be connected to the positive side of the input signal.
2. Pin 2 (Cathode): This pin is connected to the cathode of the infrared LED. It should be connected to the negative side of the input signal or ground.
3. Pin 3 (Emitter): This pin is connected to the emitter of the phototransistor. It is usually connected to the ground or the negative side of the output circuit.
4. Pin 4 (Collector): This pin is connected to the collector of the phototransistor. It is typically connected to the positive side of the output circuit or a load.
The TLP292 is used for electrical isolation between input and output, protecting circuits by allowing signals to be transferred without direct electrical connection.
