Maxim Integrated Products Inc., a reputed company that designs, manufactures, and sells analog as well as mixed-signal integrated circuits, has introduced the MAX14819. It’s a dual-channel, IO-Link master transceiver that will allow designers of Industry 4.0 applications to achieve robust communications and reduce power dissipation by 50%. 

 

The fanless programmable logic controller (PLC) and IO-Link gateway systems used in the present time must dissipate large amounts of power depending on IO configuration including the IO-Link, digital input/output, analog input/output. However with the evolution of these PLCs into new Industrial 4.0 smart factories, there is a need to achieve smarter, faster, and lower power solution while meeting IO-Link and standard IO (SIO) compliance. 

 

 

Discussing the features, the MAX14819 has a unique architecture with 50% less heat as compared to other IO-Link Master solutions and is fully compatible with all modes for IO-Link and SIO compliance. It is also equipped with robust L+ supply controllers with settable current limiting and reverse voltage/current protection help ensure robust communications with the lowest power consumption. 

 

Packed with just one microcontroller, the integrated framer/universal asynchronous receiver-transmitter (UART) allows the most scalable and cost-effective architecture. This gives way to the industry’s fastest cycle times of up to 400 microseconds and a reduced latency. 

 

Dimensionally, the MAX14819 is available in a 48-pin (7 mm x 7 mm) TQFN package and operates over the -40°C to +125°C temperature range.

 

 

• Low on-resistance, low supply current, and optimized current limiter architecture for significantly lower power consumption.

 

• 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.

 

• 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.

 

 

The MAX14819 is available for USD 6.03 (1000-up, FOB USA) at Maxim’s website and select authorized distributors. An evaluation kit MAX14819EVKIT is available for USD 99.
