Digital Isolators
Robust high-voltage isolation with precise timing and low power consumption
ISOFACE™ digital isolators are based on Infineon’s coreless transformer (CT) technology and provide robust high-voltage isolation for a broad range of applications. They are the preferred choice for isolated gate signal transfer in high-density power designs and isolating communication interfaces such as UART, CAN and SPI.
High robustness
Infineon ISOFACE ™ digital isolators provide the highest level of robustness, even in noisy environments. This is due to benchmark's highest CMTI, both TTL and CMOS input threshold options (for dual-channel digital isolators) as well as active-high and active-low output enable (for quad-channel digital isolators), integrated glitch filter, and wide supply voltage range.
Easy replacement
The products are pin-to-pin compatible and can therefore be used as a direct replacement in existing customer designs for supply security.
Accurate timing performance
The Infineon ISOFACE ™ digital isolators offer accurate timing performance, high propagation delay accuracy, and better channel-to-channel matching, which eases the system design and increases efficiency in SMPS applications.
Low power consumption
Infineon ISOFACE ™ digital isolators reduce system standby power consumption and improve system efficiency.
Certifications
ISOFACE™ digital isolators are certified according to the most stringent component isolation standard for capacitive and magnetic isolators, such as VDE0884-17, UL1577, IEC 60747-17. Furthermore, they are certified according to a wide range of system isolation standards, which eases our customer’s system certification process and accelerates their time to market.
The digital isolator continues to replace the traditional galvanic isolation transformer and opto-isolator as the predominant form of functional and safety isolation. System designers requiring a robust galvanic isolator can leverage its increased performance and power efficiency alongside decreased size and implementation costs to develop superior products faster with high safety.
Infineon’s ISOFACE™ digital isolators offer highly integrated robust galvanic isolation and superior low power consumption for use within the next generation of industrial, automotive, and consumer technologies. The ISOFACE™ digital isolator family with different channel configuration, input threshold and default output state are suitable in applications requiring basic or reinforced isolation. The dual-channel digital isolator family offers basic isolation whereas the quad-channel digital isolator family offers reinforced isolation to meet application-specific requirements.
Infineon ISOFACE™ digital isolators are used to provide galvanic isolation for safety in high-voltage applications and functional isolation for systems with different ground potentials and level shift requirements.
Digital isolators are used for isolated gate signal transfer in high-density power designs together with Infineon‘s non-isolated gate drivers in order to increase overall system efficiency. For instance, they are widely used in telecom DC/DC isolator brick applications.
In addition, Infineon’s ISOFACE ™ digital isolators are the perfect choice for isolated communication (including isolated CAN, SPI or UART) in multiple end applications such as industrial automation, telecom & servers, solar & energy storage systems, motor control and EV charging. The ISOFACE™ 4 channel digital isolators are also automotive qualified widely used in battery management systems, on-board chargers, traction inverters, DC/DC converters as well as inverters.
