Analog Devices / Maxim Integrated MAX14827A IO-Link Device Transceiver
Analog Devices MAX14827A IO-Link Device Transceiver integrates the high-voltage functions commonly found in industrial sensors, including drivers and regulators. The Analog Devices MAX14827A features two ultra-low-power drivers with active reverse-polarity protection. The operation is specified for normal 24V supply voltages up to 60V. Transient protection is simplified due to high voltage tolerance allowing micro TVS. The device features a flexible control interface. The pin control logic input allows for operation with switching sensors that do not use a microcontroller. An SPI interface with extensive diagnostics is available for sensors that use a microcontroller. For IO-Link operation, a three-wire UART interface is provided. This interface allows interfacing with the microcontroller UART. Finally, a multiplexed UART/SPI option allows using one serial microcontroller interface for shared SPI and UART interfaces.
The Analog Devices MAX14827 is available in compact TQFN-24 and WLP-25 packages and is specified over the extended -40°C to +125°C temperature range.
