Mouser Electronics, Inc. is now stocking Maxim Integrated’s MAX14827 transceiver. Claimed to be the industry’s smallest dual-channel transceiver using IO-Link® point-to-point communication technology, this transceiver lets designers incorporate intelligent sensors with continuous diagnostics and monitoring into Industry 4.0 or Industrial Internet of Things (IoT) applications.

This dual-channel transceiver, also comes with 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 2.3 Ohms, 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 Maxim MAX14827 dual-channel transceiver is now available from Mouser in a 4mm × 4mm TQFN package that is specified for ‑40 to +125 degrees Celsius. 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.
