Product Usage
The TLP120 is a phototransistor photocoupler (also known as an optocoupler or optoisolator), used to isolate different sections of a circuit to prevent high voltages from affecting the system receiving the signal. Here are some types of circuits that commonly use the TLP120:
Switching Power Supplies: To provide isolation between the high-voltage components and the low-voltage control sections.
Microcontroller Interfacing: To protect microcontrollers from high-voltage spikes and ensure safe signal transmission between different voltage domains.
Solid-State Relays: Provides isolation in controlling high-power devices with low-power signals.
Motor Control Circuits: Used for isolating the low-voltage control circuitry from motors which operate at higher voltages and generate electrical noise.
Data Communication: To prevent ground loops and electrical noise coupling between different sections of the communication system, especially in UART, SPI, and I2C interfaces.
Industrial Control Systems: Frequently used to isolate sensors and other input devices from the high-voltage industrial environment.
Medical Equipment: Provides electrical isolation to ensure patient and user safety by separating high-voltage sections from the low-voltage control circuitry.
Inverter Circuits: For isolating control electronics from the high-voltage inverter outputs.
By using an optocoupler like the TLP120, these circuits can achieve efficient isolation, improve noise immunity, and increase the safety and reliability of electronic systems.
