MAX14827 IO-Link Device Transceiver General Description Benefits and Features The MAX14827 integrates the high-voltage functions High Configurability and Integration Reduce SKUs commonly found in industrial sensors, including drivers IO-Link Compliant Transceiver and regulators. The MAX14827 features two ultra low- Auxiliary 24V Digital Output and Input power drivers with active reverse-polarity protection. 2.3 (typ) Driver On-Resistance Operation is specified for normal 24V supply voltages Selectable Driver Current: 50mA to 250mA SPI or Pin-Control Interface for Configuration and up to 60V. Transient protection is simplified due to high voltage tolerance allowing the use of micro TVS. Monitoring Multiplexed SPI/UART Interface Option The device features a flexible control interface. Pin- 5V and 3.3V Linear Regulators control logic inputs allow for operation with switching Optional External Transistor Supports Higher sensors that do not use a microcontroller. For sensors that Regulator Load Capability use a microcontroller, an SPI interface is available with Integrated LED Driver extensive diagnostics. For IO-Link operation, a three-wire UART interface is provided, allowing interfacing to the Integrated Protection Enables Robust microcontroller UART. Finally, a multiplexed UART/SPI Communication option allows using one serial microcontroller interface for 65V Absolute Maximum Ratings on Interface and shared SPI and UART interfaces. Supply Pins Allows for Flexible TVS Protection The device includes on-board 3.3V and 5V linear 9V to 60V Specified Operation Glitch Filters for Improved Burst Resilience and regulators for low-noise analog/logic supply rails. Noise The MAX14827 is available in a (4mm x 4mm) 24-pin Selectable Over-Current Auto-Retry Timing TQFN package and a (2.5mm x 2.5mm) 25-pin wafer- Thermal Shutdown Auto-Retry Cycling level package (WLP) and is specified over the extended Hot-Plug Supply Protection up to 36V -40C to +125C temperature range. Reverse Polarity Protection of All Sensor Interface Applications Inputs/Outputs Industrial sensors -40C to +125C Operating Temperature Range IO-Link sensors and actuators Ordering Information appears at end of data sheet.
