The CCE4503 is an easy-to-use device-side IO-Link compliant transceiver. It combines IO-Link compliant communication capability with advanced protection circuitry and additional features while keeping the application small and simple.

Controlled by a UART interface (TXD, RXD, TXEN), the output drivers can be configured as PNP, NPN or Push-Pull. Three LDO options and an automatic wake-up detection simplify the overall system requirements and reduce the need for additional external circuitry. The integrated protection features such as reverse-polarity protection, overcurrent protection, undervoltage detection, and thermal protection ensure robust functionality and communication.

With the small 3mm x 3mm DFN10 package size, it is especially suitable for space-limited sensor and actuator applications.

The CCE4503 IO-Link Device Transceiver is suitable for IO-Link device applications and is compliant with the IO-Link interface and system specification Version 1.1.2 from July 2013, accessible via www.io-link.org.

For a complete end-to-end system solution, Renesas also provides the CCE4510 two-channel IO-Link Master Transceiver.
