Maxim’s Low-Power Dual IO-Link Master Transceiver Tailored for Industry 4.0 Applications

Maxim Integrated MAX14819

MAX14819 delivers a fully-compliant IO-Link solution with integrated framer and L+ supply controllers

Maxim Integrated Products new MAX14819 dual-channel, IO-Link master transceiver enable designers of Industry 4.0 applications to achieve robust communications and reduce power dissipation by 50%.

The unique architecture of the MAX14819 dissipates 50% less heat compared to other IO-Link Master solutions and is fully compatible in all modes for IO-Link and SIO compliance.

Robust L+ supply controllers with settable current limiting and reverse voltage/current protection help ensure robust communications with the lowest power consumption. With just one microcontroller, the integrated framer/universal asynchronous receiver-transmitter (UART) enables the most scalable and cost-effective architecture while enabling the industry’s fastest cycle times (up to 400 microseconds) and reducing latency. The MAX14819 is available in a 48-pin (7mm x 7mm) TQFN package and operates over the -40-degree Celsius to +125-degree Celsius temperature range. Applications include IO-Link master systems and IO-Link gateways. 

Key Advantages

  • Low Power Dissipation: Low on-resistance, low supply current, and optimized current limiter architecture for significantly lower power consumption
  • High Performance: Integrated internal framer/UART enables the most flexible architecture while still achieving the fastest cycle times to achieve the lowest bill of materials (BOM) cost by eliminating the UART dependency from the microcontroller
  • Robust: 65V absolute maximum ratings and reverse polarity protection help to meet full compliance with IO-Link (1.1.2) and SIO (IEC61131-2, IEC61131-9) modes; also operates with NPN type sensors

“Maxim’s experience with implementing IO-Link into their products brings a powerful presence in our efforts to further adopt this technology in the market,” said Shinichi Motoyoshi, Chairman of Japanese PROFIBUS Organization. “With the recent launch of Japan’s IO-Link community this past April and significant growth in this market, Maxim’s new product announcement is very timely.”

“As a member of the IO-Link Consortium and the Japanese PROFIBUS Organization, products like Maxim’s new IO-Link transceiver demonstrates the company’s strong commitment to provide customers with high-performing, ultra-low power solutions for the industrial market,” said Timothy Leung, Executive Business Manager of Industrial & Healthcare at Maxim Integrated. “The MAX14819 enhances Maxim’s IO-Link technology portfolio to advance the concept of flexible manufacturing and improve both factory throughput and operational efficiency.”
