Designers can now enable smarter digital factories with the MAX22513 surge-protected, dual-driver IO-Link device transceiver with integrated DC-DC buck regulator from Maxim Integrated Products, Inc. As the industry’s smallest, most power-efficient and robust IO-Link device transceiver, it is ideal for industrial IO-Link sensors and actuator devices.
The MAX22513 continues Maxim’s leadership in enabling adaptive manufacturing for Industry 4.0 applications. By integrating the DC-DC regulator and surge protection while providing 4x lower power dissipation and 3x smaller size versus the closest competitor, Maxim continues to enable the trend towards shrinking IO-Link designs that need robust communications with faster time to market. In addition, integrated surge protection and reverse polarity ensure robust communications in harsh industrial environments to speed up the design process. The IC operates over the -40-degree Celsius to +125-degree Celsius temperature range and is available in both a 28-pin QFN package (3.5mm x 5.5mm) and a WLP (4.1mm x 2.1mm).
The highly integrated IC simplifies design process and shrinks solution size by 3x compared to closest competitor; Integrated surge protection eliminates four TVS diodes compared to Maxim’s previous solution. A 4x 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. Additionally, all four IO pins are reverse-voltage protected, 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. The MAX22513EVKIT# evaluation kit is available for $135. The MAXREFDES171# reference design is fully tested for ±1.2kV/500Ω surge protection; available at Maxim’s website
