Industry's smallest IO-Link device transceiver targets IoT applications

Mouser is now stocking the MAX14827 transceiver from Maxim Integrated. As the industry’s smallest dual-channel transceiver using IO-Link point-to-point communication technology, the MAX14827 transceiver lets designers incorporate intelligent sensors with continuous diagnostics and monitoring into Industry 4.0 or industrial Internet of Things (IoT) applications. The dual-channel transceiver integrates the high-voltage functions commonly found in industrial sensors, including drivers and regulators. The MAX14827 features two ultra-low-power drivers with active reverse-polarity protection to reduce downtime. The device provides a selectable driver current (50mA to 250mA), supports supply voltages from 24V to 60V, and includes a micro transient voltage suppressor (TVS) that increases voltage tolerance to provide transient voltage protection. In addition, the MAX14827 features a low on-resistance of just 2.3ohm, saving more than 50 percent power dissipation. The MAX14827 transceiver features a flexible control interface. The device offers pin-control logic inputs that allow for operation with switching sensors that do not use a microcontroller, as well as an SPI interface with extensive diagnostics for sensors that use a microcontroller. Engineers can alternatively use a three-wire UART interface for IO-Link operation and a multiplexed UART/SPI option, which enables one serial microcontroller interface for shared SPI and UART interfaces. The device also includes onboard 3.3V and 5V linear regulators for low-noise analog and logic supply rails. The device is available in a 4mm × 4mm TQFN package with a 40C to +125C temperature range. Mouser is also stocking the MAX14827EVKIT evaluation kit, which allows engineers to test the onboard MAX14827 transceiver. The evaluation board includes power-supply and regulator input and output pins connected to convenient connectors for easy probing. The board’s device logic input and output pins also feature convenient connectors for logic testing.
