Transceiver has integrated DC/DC regulator for surge protection
9 April 2019 
Claimed to be the smallest and most power-efficient dual-driver IO-Link transceiver to date, the MAX22513 is three times smaller and with four time lower power dissipation, claims the company.
It is designed for industrial IO-Link sensors and actuator devices, to meet the demands of industry 4.0 for smarter, sensor and actuator devices which are smaller and more robust, while dissipating less power.
Integrated surge protection and reverse polarity ensure robust communications in harsh industrial environments to speed up the design process, says the company. All four IO pins are reverse-voltage protected, short-circuit protected and feature ±1kV/500Ω surge protection. The company adds that integrated surge protection eliminates four TVS diodes compared to its earlier transceiver solution.
The IC operates over the -40 to 125°C range and is available in both a 28-pin QFN package (measuring 3.5 x 5.5mm) and a WLP (measuring 4.1 x 2.1mm).
The MAX22513EVKIT# evaluation kit and MAXREFDES171# reference design are also available.
