IO-Link master transceiver dissipates 50% less heat
Article By : EDN Asia
The MAX14819 is fully compatible in all modes for IO-Link and SIO compliance, according to Maxim.
Maxim Integrated Products has introduced a dual-channel, IO-Link master transceiver, which claims to reduce power dissipation by 50%.
Today's fanless programmable logic controller (PLC) and IO-Link gateway systems must dissipate large amounts of power depending on IO configuration (IO-Link, digital input/output, analog input/output). As these PLCs evolve into new Industrial 4.0 smart factories, special attention must be considered to achieve smarter, faster and lower power solutions while also meeting IO-Link and standard IO (SIO) compliance, according to the company.
The MAX14819 is designed to dissipate 50% less heat compared to other IO-Link Master solutions and is fully compatible in all modes for IO-Link and SIO compliance, according to Maxim. L+ supply controllers with settable current limiting and reverse voltage/current protection help ensure communication with the lowest power consumption.
With just one microcontroller, the integrated framer/universal asynchronous receiver-transmitter (UART) enables a scalable and cost-effective architecture while enabling up to 400ms cycle time and reducing latency, according to the company.

The MAX14819 is available in a 48-pin, 7mm x 7mm TQFN package and operates over the -40°C to 125°C range. Applications include IO-Link master systems and IO-Link gateways.
The MAX14819 is available for $6.03 for a minimum of 1,000-piece order at Maxim's website and select authorised distributors.
