Industry 4.0 application designers can now achieve robust communications and reduce power dissipation by 50% with the MAX14819 Dual IO-Link Master Transceiver from Maxim Integrated Products, Inc.Current fanless programmable logic controllers (PLCs) and IO-Link gateway systems dissipate significant amounts of power depending on the IO configuration (IO-Link, digital input/output, analog input/output). As these PLCs become the new smart factories of Industry 4.0, special attention must be paid to achieving smarter, faster, and lower-power energy solutions while simultaneously complying with IO-Link and the SIO standard.
Maxim continues to provide a portfolio of advanced factory automation solutions that pave the way for Industry 4.0. The unique architecture of the MAX14819 dissipates 50% less heat compared to other IO-Link Master solutions and is fully compliant with all IO-Link and SIO compliance modes. Robust L+ power drivers with adjustable current limiting and reverse voltage/current protection help ensure robust communications with the lowest power consumption. With a single microcontroller, the integrated Universal Asynchronous Transmitter/Transmitter (UART) enables the most scalable and cost-effective architecture, while also allowing faster cycle times (up to 400 microseconds) and reducing latency. The MAX14819 is available in a 48-pin (7 mm x 7 mm) TQFN package and operates over a temperature range of -40°C to +125°C. Applications include IO-Link master systems and IO-Link gateways.
Key advantages
- Low power dissipation: Low resistance, low supply current and an optimized current limiter architecture for significantly lower power consumption
- High performance: The integrated internal framer/UART allows for the most flexible architecture while achieving the fastest cycle times to achieve the lowest bill of materials (BOM) cost by eliminating the microcontroller's UART dependency
- Robust: Absolute maximum values of 65V and reverse polarity protection help comply with IO-Link (1.1.2) and SIO (IEC61131-2, IEC61131-9) modes; also works with NPN type sensors.
