Analog Devices / Maxim Integrated MAX14828 IO-Link Device Transceiver

Analog Devices MAX14828 IO-Link Device Transceiver integrates high-voltage functions in industrial sensors and has one ultralow-power driver (C/Q) with active reverse-polarity protection. The MAX14828 features an auxiliary digital input and a UART interface that allows for firmware updates. A high voltage tolerance allows the use of micro TVS and simplifies transient protection.

The Analog Devices MAX14828 features a flexible control interface. Pin-control logic inputs allow for operation with switching sensors that do not use a microcontroller. For sensors that use a microcontroller, an SPI interface is available with extensive diagnostics.

For IO-Link operation, a UART interface is provided, allowing interfacing to the microcontroller UART. A multiplexed UART/SPI option allows using one serial microcontroller interface for shared SPI and UART interfaces.
