FAQ about Digital Isolators
-
1. What is a digital isolator?
A digital isolator is a device that realizes signal transmission under electrical isolation. It is widely used in various electronic system equipment such as industrial control, power energy, communication networks, instrumentation, consumer electronics, etc. Its core function is to isolate different circuits at the electrical level, effectively preventing high voltage or noise signals from interfering with low voltage circuits, thereby improving the overall reliability, anti-interference ability and safety of the system.
Basic concepts and functions of digital isolators
Digital isolators transmit signals through light, electromagnetic or other means, while ensuring that there is no direct electrical connection between the two circuits, thereby providing electrical isolation. Its main functions include:
Signal isolation: prevent high voltage or noise signals from interfering with low voltage circuits.
Anti-interference ability: isolate electromagnetic interference (EMI) and radio frequency interference (RFI), and improve the stability of data transmission.
Safety: protect low voltage circuits and microcontrollers in high voltage or potentially dangerous working environments to prevent accidents.
Signal conversion: convert signals between different levels and voltage domains, and be compatible with multiple power supply voltages.
Data integrity: reduce the impact of ground loops and other potential interference sources, and improve the integrity and accuracy of data transmission.
Working principle of digital isolator
The working principle of digital isolator is mainly based on the following technologies:
Optical coupling mechanism: Use light-emitting diodes and photosensitive elements (such as photodiodes or phototransistors) to convert optical signals. The design is simple and low-cost, suitable for low-speed signal transmission, but the transmission speed is slow.
Electromagnetic coupling: Signal transmission through transformers or electromagnetic waves, suitable for high-bandwidth applications, but the design is complex and may be affected by the magnetic field environment.
Capacitive coupling: Electrical isolation of signals is achieved through capacitors, suitable for high-speed signal transmission, but the performance of low-frequency signal transmission is poor.

2. What is the difference between optical isolators and digital isolators?
The main difference between optical isolators and digital isolators lies in their working principles, performance and application scenarios.
Working principle
Optical isolators (also known as optocouplers) use light to transmit signals through isolation barriers. It emits light through light-emitting diodes (LEDs), and photosensitive transistors receive light and convert it into electrical signals, thereby realizing isolated transmission of signals.
Digital isolators use capacitive or electromagnetic isolation technology to transmit signals. They achieve signal isolation transmission through capacitive coupling or electromagnetic isolation, with higher transmission rate and lower power consumption.
Performance comparison
Optical isolators have a slower transmission rate, usually several megabits per second, and require additional circuit components, increasing costs and PCB area. In addition, the aging problem of optical isolators is more serious, especially when working in a high temperature environment.
Digital isolators have higher transmission rates, lower power consumption and smaller size. They also have better common mode transient immunity (CMTI) and longer service life, and are more integrated, and can integrate multiple functions such as input filters, transceivers and output enable options. Digital isolators have no temperature drift problems and better performance consistency.

3. What is an electronic isolator?
An electronic isolator is an electronic component used to achieve electrical isolation in a circuit. It is mainly used to prevent the flow of current while allowing electrical signals or energy to be transmitted in some way. It ensures the safety of equipment and people by isolating the electrical connections between different circuits.
Definition and function
Electronic isolators effectively isolate the electrical connections between two circuits by using components with special structures to prevent current, signals or interfering substances from being transmitted between the two circuits. Its main functions and effects include:
Safety isolation: prevent high voltage or high power circuits from affecting low voltage or low power circuits, and protect the safety of equipment and personnel.
Electrical isolation: prevent noise, surges and interference in the power supply from propagating to other circuits, and improve the stability and reliability of the circuit.
Signal isolation: isolate the ground loop during signal transmission to avoid signal interference and signal loss.
Baud isolation: in digital communication or data transmission, isolate the data transmission loop to protect the receiver from potential electrical interference and attacks.
Types and application areas
There are many types of electronic isolators, including:
Air isolator: uses air as a medium, with a simple structure and high reliability.
Gas isolator: uses gas medium to achieve circuit isolation, suitable for high voltage environments and high power circuits.
Liquid isolator: uses insulating liquid as a medium, suitable for high voltage scenarios, with good insulation performance and heat dissipation effect.
