CCE4503
IO-Link Device IC General Description
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 an 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 a robust functionality and
communication. With the small 3mm x 3mm DFN10 package size, it is especially suitable for space
limited sensor and actuator applications. Key Features
