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

EL817(S)(TB)-VG

A phototransistor optocoupler, the EL817(S)(TB)-VG is frequently employed in applications where electrical isolation between the input and output is necessary for signal integrity, safety, and noise reduction. This component consists of an infrared LED and a phototransistor, encapsulated in a package that allows optical communication between the two, effectively isolating the electrical circuits on either side.

Application Scenarios

EL817(S)(TB)-VG is widely used in various applications, such as power supply regulation, digital logic interfaces, microcontroller input/output isolation, and signal transmission across different voltage domains. A specific application scenario could be its use in an isolated UART communication interface, where it provides isolation between a microcontroller and a serial communication line.

Parameter Features

The key features of EL817(S)(TB)-VG include a high isolation voltage (often around 5000V RMS), a current transfer ratio (CTR) that indicates the efficiency of the optical coupling, and a wide operating temperature range. It typically operates in a straightforward manner, with the LED being driven by an input signal, which in turn modulates the conductivity of the phototransistor on the output side.

Circuit Connection Example: Isolated UART Communication Interface

In an isolated UART communication interface, EL817(S)(TB)-VG can be used to isolate the transmit (TX) and receive (RX) lines between a microcontroller and an external UART device, such as a serial port on a PC or another microcontroller.

- Power Supply Connections: Ensure that the anode and cathode of the internal LED are connected to a suitable power source, typically through a current-limiting resistor. The phototransistor's collector is often connected to the positive supply voltage via a pull-up resistor, while the emitter is typically connected to ground.

- Input Signal to LED: Use a current-limiting resistor to connect the microcontroller's TX line to the LED's anode. The LED's cathode is linked to the ground. This setup modulates the LED based on the TX data signal.

- Phototransistor Output: Connect the collector of the phototransistor to the RX line of the external UART device through a pull-up resistor. The emitter is connected to the ground. The phototransistor conducts based on the light from the LED, recreating the TX signal on the RX line, but electrically isolated.

- JTAG Interface Not Applicable: For a device like EL817(S)(TB)-VG, a JTAG interface is not applicable as it's not a programmable device. It functions purely as an optoelectronic isolator.

When designing circuits with EL817(S)(TB)-VG, consider the current requirements of the LED and the phototransistor's response time to ensure that the data signals are transmitted accurately without distortion. The choice of current-limiting and pull-up resistors is crucial to ensure that the LED and phototransistor operate within their specified parameters. Additionally, ensure that the isolation voltage rating of the optocoupler meets the safety requirements of the application, especially in scenarios involving high voltage levels. Proper PCB layout practices should be followed to maintain the isolation barrier's integrity and minimize noise coupling between the input and output.
