Maxim Claims Smallest, Most Efficient Dual IO-Link Transceiver with DC-DC Regulator and Surge Protection

April 10, 2019 Alix Paultre

Maxim Integrated’s MAX22513 surge-protected, dual-driver IO-Link device transceiver with integrated DC-DC buck regulator is presented as the industry’s smallest, most power-efficient and robust IO-Link device transceiver, ideal for industrial IO-Link sensors and actuator devices. The MAX22513 integrates the DC-DC regulator and surge protection while providing up to 4x lower power dissipation and 3x smaller size versus legacy solutions. 

Integrated surge protection and reverse polarity ensure robust communications in harsh industrial environments, and the IC operates over the -40° to +125°C temperature range and is available in both a 28-pin QFN package (3.5mm x 5.5mm) and WLP (4.1mm x 2.1mm). The lower power dissipation is enabled by low 2Ω (typical) on-resistance drivers, as well as a 300mA (maximum load) DC-DC regulator with 80 percent efficiency. All four IO pins are reverse-voltage and short-circuit protected, and feature ±1kV/500Ω surge protection.

The MAX22513 is available at Maxim’s website for $3.75 (1000-up, FOB USA); also available from authorized distributors, and the MAX22513EVKIT# evaluation kit is available for $135.

The MAXREFDES171# reference design is fully tested for ±1.2kV/500Ω surge protection.
