Pin Function and Specifications
The HCPL-2630-500E optocoupler is a 6-pin component with the following pinout:
Pin Number Pin Name Function Description 1 Anode (A) The anode of the internal LED . 2 Cathode (K) The cathode of the internal LED. 3 Not Used This pin is not connected internally and can be left floating. 4 Output Collector (C) The collector of the photo transistor , used to connect to the external circuitry. 5 Output Emitter (E) The emitter of the phototransistor. 6 Vcc (Supply Voltage) The positive supply voltage pin for the phototransistor side. Typically, 5V or 3.3V.Circuit Principle and Function
The HCPL-2630-500E works based on an optical isolation principle. It consists of an LED and a phototransistor. The LED emits light when a voltage is applied across it (between pins 1 and 2). The phototransistor (between pins 4 and 5) detects this light, causing a change in its conductivity, which in turn controls the output signal on the external circuit connected to pin 5.
Detailed Pinout Functions:
Pin 1 (Anode of LED): The input side of the optocoupler. When a voltage is applied here (usually via a resistor), the internal LED turns on and emits light. The brightness of the LED determines the current through the phototransistor and controls the output signal.
Pin 2 (Cathode of LED): This pin is connected to the negative side of the LED inside the device. It is generally tied to ground in the circuit.
Pin 3 (No Connection): This is a non-functional pin, and it has no internal connection. This pin can be left floating.
Pin 4 (Collector of Phototransistor): The collector of the phototransistor is used to carry the output signal. This pin is typically connected to the external circuit and can be used to drive logic gates or other components based on the signal from the LED.
Pin 5 (Emitter of Phototransistor): The emitter of the phototransistor outputs the signal from the optocoupler. It is connected to the external ground in most circuit configurations.
Pin 6 (Vcc): This is the supply voltage for the phototransistor side of the optocoupler. Typically, a 5V or 3.3V power supply is used for the Vcc pin.
