Dual IO-Link transceiver shrinks for industry 4.0

Claimed to be the industry’s smallest, most power-efficient and robust IO-Link device transceiver, the MAX22513 is designed for industrial IO-Link sensors and actuator devices in smart, digital factories.

The MAX22513 surge-protected, dual-driver IO-Link device transceiver has an integrated DC/DC buck regulator. Maxim Integrated Products claims that integrating the DC/DC regulator and surge protection while providing four times lower power dissipation enabled by low (2 Ohm) typical on resistance drivers and a maximum load of 300mA DC/DC regulator with 80 per cent efficiency. It is also three times smaller size versus the closest competitor, claims Maxim. Integrated surge protection and reverse polarity ensure robust communications in harsh industrial environments to speed up the design process, adds Maxim.

The IC operates over the -40 to +125 degrees C temperature range and is available in both a 28-pin QFN package (3.5 x 5.5mm) and a WLP (4.1 x 2.1mm).

The integration of surge protection eliminates four TVS diodes compared to Maxim’s previous solution.

All four IO pins are reverse-voltage protected, short-circuit protected and feature ±1kV/500 Ohm surge protection for secure communications.

The MAX22513 is available now, together with the MAX22513EVKIT# evaluation kit  and the MAXREFDES171# reference design which is fully tested for ±1.2kV/500 Ohm surge protection.
