Recycle Infineon Isolation Product:Digital Isolator,ISOFACE™ Digital Input and Output IC

The Infineon ISOFACE™ isolation product range is based on the company’s proprietary core-less transformer (CT) isolation technology. It is divided into two main categories: standalone digital isolators and digital input/output ICs with integrated isolation. These products are designed for high-noise, high-voltage applications such as industrial automation, PLCs, servo drives, energy storage, photovoltaics and robotics. It enables reliable electrical isolation, signal transmission and channel diagnostics between the control-side MCU and the 24V process side in the field, replacing traditional optocoupler solutions and overcoming the challenges associated with optocoupler ageing, temperature drift and reduced service life.

1. ISOFACE™ Digital Isolators

The ISOFACE™ digital isolator comprises series such as the dual-channel 2DIBx4xxF and the four-channel 4DIRx4xxH. These are general-purpose isolated signal transmission devices, primarily designed for isolated communication and isolated drive signal transmission.

The core technology utilises an on-chip core-less transformer isolation structure, featuring high common-mode transient immunity (CMTI ≥ 100 kV/µs) to withstand severe industrial dv/dt noise interference; It supports signal rates of up to 40 Mbps, operates within a temperature range of –40 °C to +125 °C, offers stable timing offset and low power consumption, and supports various channel direction configurations (combinations of forward and reverse channels). It features a built-in fail-safe default output state, with isolation levels meeting enhanced isolation standards, and is accompanied by component-level and system-level safety certifications.

Suitable applications: isolated SPI, CAN and UART communication interfaces; isolated power gate drive signals; energy storage converters; photovoltaic inverters; industrial server power supplies; and main control signal isolation for humanoid robots, amongst others. Packages include both narrow-body and wide-body DSO variants, facilitating high-density PCB layout. Long-term availability models can be directly substituted for similar isolators, reducing material iteration costs.

2. ISOFACE™ Digital Input and Digital Output ICs

ISOFACE™ digital input ICs (representative models: ISO1I813T, ISO2I828V) and digital output ICs (e.g. ISO1H812G) are integrated isolated I/O front-end chips. Unlike standalone digital isolators, they integrate 24V field-side I/O interface circuits, channel protection and diagnostic functions with the isolation chain onto a single chip, making them core solution chips for PLCs and remote I/O modules.

The digital input ICs are compatible with the IEC 61131-2 standard and support the acquisition of 24V industrial sensor signals. They can be configured for Type 1 or Type 3 sensor detection, with up to 8 channels per chip, with independent current regulation, overcurrent and short-circuit diagnostics per channel, and the ability to report fault locations individually. The isolation layer completely separates the high-voltage field side from the low-voltage MCU side, with a maximum junction temperature tolerance of 135°C, making it suitable for harsh operating conditions.

The digital output IC incorporates isolated drive channels, short-circuit protection, open-circuit detection and power supply monitoring. It can directly drive field solenoid valves, indicator lights and actuators, simplifying the use of discrete peripheral components, significantly reducing the PCB footprint of I/O modules and improving equipment uptime. It is widely used in automated production lines, collaborative robots and wind power control modules.

Common product advantages: Isolation performance does not degrade over time; long-term reliability is superior to optocoupler solutions; isolation design workload is reduced; and channel diagnostic functions facilitate equipment operation and maintenance, enabling rapid identification of faulty channels.

II. Buyer’s Guide

1. Key Considerations for Selection

Prioritise clarifying requirements: if only isolated communication or isolated signal transmission is required, select the ISOFACE™ standalone digital isolator; if direct connection to 24V field sensors and actuators is required, acting as a PLC I/O front-end, select the ISOFACE™ digital input/output IC.

Channel configuration: Select dual-channel or quad-channel digital isolators as required, and confirm the channel direction (forward or reverse) and the default high or low level in the event of a fault; for I/O ICs, verify that the number of channels, sensor types, output drive capability and diagnostic functions match the PLC specifications.

Specification verification: Pay particular attention to the isolation withstand voltage, CMTI, maximum data rate and operating temperature class; For industrial-standard products, prioritise models with IEC safety certification; for automotive and special operating conditions, separately verify AEC-Q and functional safety documentation.

Availability and Alternatives: The Infineon ISOFACE series includes both continuously available and discontinued models; verify the status of each model before procurement to avoid discontinued parts; set aside alternative components for the project to mitigate single-source risks.

Procurement channel recommendations: Give priority to official authorised channels and reliable stock suppliers; for high-volume projects, secure delivery dates in advance; for small-batch prototyping, apply for evaluation boards to validate the solution.

2. Application Design Considerations

Strictly adhere to the safety requirements in the datasheet regarding insulation clearance and creepage distance; isolate power zones, with independent power supplies on both sides of the isolation; route wiring away from areas with power switch noise; utilise the chip’s built-in diagnostic pins for fault detection in the upper-layer software.

III. Mingjiada Electronics | Electronic Component Recycling Details and Delivery Process

Shenzhen Mingjiada Electronics provides electronic component recycling services for factories, automation integrators, traders and solution providers.
