IO-Link Transceiver with Integrated Protection


  • High Configurability and Integration Reduces SKU
  • Integrated Protection Enables Robust Systems
  • Optimized for Small Designs
  • Flexible control interface

The MAX22515 low-power industrial transceiver can operate as either an IO-Link device or a non-IO-Link sensor transceiver in industrial applications. The MAX22515 features a selectable control interface (pin mode or I2C), two integrated linear regulators, and integrated surge protection for robust communication. The transceiver includes one C/Q input-output channel and one digital input (DI) channel. 

The device features a flexible control interface. Pin-control logic inputs allow for operation with switching sensors that do not use a microcontroller.
