SFH6916 Typical application Circuitry

SFH6916

The SFH6916 is an optocoupler chip that serves as an interface between two electrical circuits, providing electrical isolation while transmitting signals between them. This component is commonly used in various applications where galvanic isolation is needed to protect sensitive components or circuits from voltage spikes, noise, or other disturbances. It consists of an infrared emitter (LED) and a phototransistor within a single package.

Key Features of SFH6916:

- Phototransistor Output

- Optically Coupled Isolation

- High Isolation Voltage (up to several kV)

- Fast Response Time

- Compact DIP-4 Package

Example Application: Isolated Voltage Sensing

In an application where you need to measure an isolated voltage and transmit it to another circuit safely, you can use the SFH6916. Let's design a detailed circuit for this scenario:

Circuit Overview:

We'll create a circuit to sense an isolated voltage from a source and transmit it to a microcontroller without a direct electrical connection, using the SFH6916 optocoupler.

Circuit Components:

- SFH6916 optocoupler

- Microcontroller (MCU)

- Voltage source to be sensed (Vs)

- Resistor (R1)

- Resistor (R2)

Circuit Connections:

1. Connect the anode (A) of the SFH6916's LED to the MCU's output pin for controlling the LED, labeled "LED_CTRL."

2. Connect the cathode (K) of the SFH6916's LED to the ground (GND) of the MCU.

3. Connect the collector (C) of the SFH6916's phototransistor to the MCU's analog input pin for voltage sensing, labeled "AIN."

4. Connect the emitter (E) of the SFH6916's phototransistor to the ground (GND) of the MCU.

5. Place resistor R1 in series with the Vs source, and connect one end to Vs and the other end to the anode of the LED (A).

6. Connect resistor R2 between the anode of the LED (A) and ground (GND).

Operation:

1. When the MCU activates the LED_CTRL pin by driving it high, current flows through the LED, emitting infrared light.

2. The emitted light is detected by the phototransistor, causing it to conduct between its collector and emitter.

3. The current through the phototransistor depends on the voltage across resistor R1, which is proportional to Vs.

4. The MCU reads the voltage across resistor R2, which is directly related to the current through the phototransistor.

5. By measuring the voltage at AIN, the MCU can calculate the isolated voltage Vs.

Considerations:

- Select appropriate resistor values (R1 and R2) to ensure the phototransistor operates within its specified current range.

- Ensure that the LED current and phototransistor current meet the SFH6916's datasheet recommendations.

- Pay attention to the power supply voltage and current requirements of the MCU.

- Optimize the circuit for noise immunity and safety to achieve accurate voltage sensing and isolation.
