EL817(S)(TA)-VG Typical application Circuitry

EL817(S)(TA)-VG

EL817(S)(TA)-VG is an optocoupler or optical isolator component, which includes an infrared emitting diode (LED) and a phototransistor. This device is primarily used to provide electrical isolation between the input and output, ensuring that high voltages or noise on one side do not affect the other side. It's commonly utilized in situations where signal integrity and isolation are paramount, such as in industrial controls, power supplies, and communication systems.

Application Scenarios

EL817(S)(TA)-VG is versatile and finds application in various domains, including but not limited to, isolating digital signals between a microcontroller and high-power devices, signal noise isolation in sensitive circuits, and as a part of the interface in communication systems to prevent ground loops. A specific application scenario could be its use in isolating a microcontroller from a motor driver circuit in a robotics project.

Parameter Features

Key features of the EL817(S)(TA)-VG include its high isolation voltage, typically in the range of several thousand volts, which ensures robust electrical isolation. It also has a specified Current Transfer Ratio (CTR), indicating the efficiency of the optical coupling from the LED to the phototransistor. The device is designed to operate over a wide temperature range, making it suitable for various environments.

Circuit Connection Example: Microcontroller to Motor Driver Isolation

In a robotics project where a microcontroller controls a motor driver, EL817(S)(TA)-VG can be used to isolate control signals sent to the motor driver, protecting the microcontroller from potential high voltages and noise.

- Power Supply to LED: Connect the anode of the internal LED to a digital output pin of the microcontroller through a current-limiting resistor, and connect the cathode to the ground of the microcontroller circuit. This setup enables the microcontroller to activate the LED within the EL817(S)(TA)-VG based on control signals.

- Phototransistor Output: Connect the collector of the phototransistor to the control input of the motor driver circuit and the emitter to the ground of the motor driver circuit. Use a pull-up resistor at the collector to ensure a defined logic level when the phototransistor is not conducting.

- Current-Limiting Resistor: Choose a resistor value that limits the LED current to safe levels, based on the forward voltage and desired current specified in the datasheet for EL817(S)(TA)-VG.

- Pull-Up Resistor: Place a pull-up resistor at the collector of the phototransistor to pull the motor driver control input to a known high state when the LED is off and the phototransistor is not conducting.

When designing circuits with EL817(S)(TA)-VG, consider the current requirements of the LED to ensure proper operation without exceeding the maximum ratings. Also, account for the CTR to ensure that the phototransistor can adequately drive the subsequent stage in the motor driver circuit. The isolation voltage rating of EL817(S)(TA)-VG should be higher than any potential voltage difference across the isolation barrier to ensure safety and reliability. Proper PCB layout practices are essential to maintain the integrity of the electrical isolation and to minimize coupling between the input and output.
