Maxim Integrated Releases MAXREFDES177 IO-Link Reference Design

October 30, 2020 Perry Cohen

Maxim Integrated released the MAXREFDES177 IO-Link reference design. The new development kit highlights the flexibility of the MAX22515 IO-Link transceiver, all while configuring all modes of the MAX2200 software-configurable analog IO.

The IO-Link interfaces provides the ability to have all IO-Link sensors, actuators, or IO expansion modules to be interchangeable to a hardware interface. Software-defined performance parameters and selectable analog input or output performance modes are also provided.

IO-Link & Software-Configurable IO Product information per a company press release:

  • MAX22000: The software-configurable analog IO provides up to more than half the power savings and approximately half the size compared to the closest competitive solutions on the market. Key functions integrated include a 24-bit ADC analog input mode and an 18-bit DAC analog output mode, as well as operations over either a single 2-wire interface or a 4-wire resistance temperature detector (RTD)/thermocouple temperature measurement.
  • MAX22515: The MAX22515 is the industry’s smallest ±1.2kV/500Ω surge-protected, single-channel IO-Link transceiver. It features high integration with protection diodes, auxiliary digital input, I2C or pin control, integrated oscillator and selectable 3.3V or 5V LDO which help to provide high configurability and reduce SKU. It enables half the power dissipation due to low 2.2Ω or 2.65Ω (typ) C/Q driver on-resistance compared to the closest competitor, in the smallest 2.5mm x 2.0mm WLP package. It cuts the solution size up to 67% compared to the closest competitor and fits into small, space-constrained IO-Link sensors or actuators.

The MAXREFDES177# reference design is available at Maxim Integrated’s website for $65.
