Industry’s smallest IO-Link transceiver halves power dissipation

Industrial systems designers are now offered a robust IO-Link dual-channel transceiver that dissipates the lowest heat in the smallest package with the MAX14827 from Maxim Integrated Products. The Industry 4.0 revolution is enabling smarter factories to increase productivity and manufacturing flexibility. IO-Link sensors enable this revolution by bringing intelligence and control down to the factory floor. Sensors are getting smaller and need to deliver more functionality, while ensuring robust communications. Power is also critical because these sensors are small and it is difficult to dissipate heat. The MAX14827 dual-channel, 250mA transceiver meets these requirements, while also integrating high-voltage functions commonly found in industrial sensors, including drivers and regulators. It features two ultra-low power drivers with active reverse-polarity protection to reduce downtime. For sensors that use a microcontroller, a SPI interface is available with extensive diagnostics. For IO-Link operation, a three-wire UART interface is provided, allowing interfacing to the microcontroller UART. Finally, a multiplexed UART/SPI option allows using one serial microcontroller interface for shared SPI and UART interfaces. The device includes on-board 3.3V and 5V linear regulators for low-noise analog/logic supply rails, says the company. Key features : 1 - Lower On-Resistance (RON): 2.5ohm Ron (typical) saves more than 50% power dissipation. 2 - Tiny WLP Package: saves 60% space. 3 - Robust 65V Abs Max: enables flexible TVS protection selection. 4 - High Integration and Configurability: Reduces SKU’s with selectable PP, NPN, PNP output. “The MAX14827 has the lowest drop voltage for a dual transceiver in the smallest package,” said Tim Leung, senior business manager, Maxim Integrated. “Maxim’s commitment to IO-Link and working with our customers on designs that have passed surge and burst enables us to consistently deliver robust products for the industrial market.”
