MAXREFDES171#

The MAX22513 dual-channel low power IO-Link device transceiver features a selectable control interface, internal high-efficiency DC-DC buck regulator, two internal linear regulators, and integrated surge protection for robust communication. The device features low-on resistance drivers (C/Q and DO/DI), selectable driver current limits, and overcurrent protection to reduce power dissipation in small sensor applications. The DC-DC buck regulator supplies up to 300mA load current and has an adjustable output voltage (from 2.5V to 12V). Internal linear regulators generate 5V and 3.3V, supplying up to 50mA of current. The MAX22513 can be controlled using SPI or I2C interfaces, providing flexibility for microcontrollers, and extensive control and diagnostic features. Both full- and half-duplex SPI are supported. The internal MCLK oscillator provides a clock source to a microcontroller for IO-Link communication.
