What are edge-based and OOK digital isolator architectures?
Edge-based and on-off-keying (OOK) are common communication architectures used in digital isolators. The choice between the two involves tradeoffs, mostly in data rates versus power consumption. Depending on the implementation, there can also be tradeoffs related to noise and transient response and common mode transient immunity (CMTI). This FAQ reviews how edge-based and OOK architecture […]
How does digital isolation contribute to sustainability?
In general, digital isolation can be implemented using capacitive, giant magneto restrictive (GMR), and magnetic technologies. The digitally isolated gate drivers used to drive silicon carbide (SiC) and gallium nitride (GaN) devices plus silicon power MOSFETs and IGBTs in green energy systems like electric vehicles (EVs) and solar inverters mostly rely on magnetic isolation techniques, […]
What’s a digitally isolated transceiver?
Digitally isolated transceivers are available for industrial applications, electric vehicles, satellites, communications, data processing, and medical systems. They are available for specific protocols like control area network (CAN), RS485, RS422, and RS232, serial peripheral interface (SPI), I2C, low-voltage differential signaling (LVDS), and others. Some support multiple protocols. They can have a single channel or multiple […]
What technologies are used for digital isolators?
There are three main technologies used for digital isolators, capacitive, magnetic, and giant magnetoresistive (GMR). This FAQ briefly looks at capacitive designs (they are covered in more detail in “What is a capacitive digital isolator”), then digs deeper into magnetic and GMR devices. Capacitive digital isolators use two CMOS dies connected with a capacitive isolation […]
What are the key specifications of digital isolators? Part 2
Digital isolators have two primary functions, to provide isolation and to transmit information across the isolation barrier. Part one looked at the various specifications related to voltage and isolation performance. Part two details key specifications related to the transmission of information. Common‐mode transient immunity (CMTI) is one of three key specifications of digital isolators. The […]
What are the key specifications of digital isolators? Part 1
Digital isolators have two primary functions, to provide isolation and to transmit information across the isolation barrier. This first of two FAQs on digital isolator specifications looks at voltage and isolation specs. Part two details key specifications related to information transmission. Two basic voltage specs are: Working voltage (VIOWM) is the maximum rms, or corresponding […]
What is a capacitive digital isolator?
Capacitive digital isolators comprise two digital CMOS dies connected with a capacitive isolation barrier. The barrier provides galvanic isolation to meet safety regulations, reduce noise from ground loops, and connect interface communication boards or subcircuits that operate with different supply voltages. They are used in power converters and motor drives, electric vehicles (EVs), consumer devices, […]
