Maxim Integrated's MAX22000 and MAX22515 chipset solutions take full advantage of IO-Link's bidirectional universal interface. The IO-Link interface allows each IO-Link sensor, actuator or IO expansion module to interact with the standard hardware interface. The chipset solution also provides software-defined performance parameters and optional analog input or output operating modes. MAXREFDES177# IO-Link reference design integrates these functions and is used to demonstrate flexible software configuration capabilities.

IO-Link and software configurable IO products:

• MAX22000: Software configurable analog IO, its power consumption and size are half of the closest competitive product, and its temperature drift is 2 times lower than the closest competitive solution, thus supporting high-precision temperature calibration. Key features include 24-bit ADC analog input mode and 18-bit DAC analog output mode, and work in 2-wire or 4-wire resistance temperature detector (RTD)/thermocouple temperature measurement.
• MAX22515: IO-link transceivers consume only one-fourth of the power consumption and only one-half of the size compared with the closest competitors. MAX22515 is the industry's smallest single-channel IO-Link transceiver with ±1.2kV/500Ω surge protection. This highly integrated device includes protection diodes, auxiliary digital inputs, I2C or pin control, built-in oscillators and optional 3.3V or 5V LDOs, helping to provide high configurability and reduce SKUs. The on-resistance of the C/Q driver stage of the device is only 2.2Ω or 2.65Ω (typical value), and the minimum 2.5mm x 2.0mm WLP package is adopted, which reduces heat loss by 4 times. Compared with the closest competitor product, the solution size is reduced by 50%, and it is suitable for IO-Link sensors or actuators with small size and limited space.

Key advantage

• flexibility: The software can define IO and adjust equipment parameters in real time, which helps to greatly optimize machine performance and reduce plant downtime.
• Efficient: MAX22000 and MAX22515 are optimized to achieve the best energy-saving standards in the industry, and the power consumption is one-half and one-fourth of competing solutions, respectively.
• Small size: MAX22515 provides the smallest single-channel IO-Link footprint, less than 5mm²; MAX22000 footprint is 86mm². Both products are 50% smaller than other solutions on the market.
