Dual IO-Link master transceiver; 50% lower power for Industry 4.0 comms

New Products |
Designers of Industry 4.0 applications can achieve robust communications and reduce power dissipation by 50% with the MAX14819 dual-channel, IO-Link master transceiver, according to makers Maxim Integrated. The part is a fully-compliant IO-Link device with integrated framer and L+ supply controllers.

Maxim has a portfolio of advanced factory automation solutions that creates pathways toward achieving Industry 4.0. The 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 a single microcontroller, the integrated framer/UART enables the most scalable and cost-effective architecture with fastest cycle times (up to 400 µsec) and reducing latency. The MAX14819 is available in a 48-pin (7 x 7 mm) TQFN package and operates over the -40 to +125-degree Celsius temperature range. Applications include IO-Link master systems and IO-Link gateways.

Its low on-resistance switches, low supply current, and optimized current limiter architecture yield significantly lower power consumption; the 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


MAX14819 is priced at $6.03 (1000); an evaluation kit is $99 (MAX14819EVKIT). The respective MAXREFDES145# reference design is available at; https://www.maximintegrated.com/products/MAXREFDES145 and a video clip is at;
