The MAX22514 IO-Link transceiver integrates high voltage functionality, including one 24V line driver, an integrated DC-DC buck regulator, and 5V and 3.3V linear regulators. The MAX22514 is targeted for IO-Link devices, masters, and industrial switching sensor applications, and can be configured and monitored using a standard SPI interface.

Applications

• IO-Link and Industrial Sensor and Actuator Devices
• The MAX22514 features a SPI interface for configuration and diagnostics. A high level of integration (including two linear regulators, a DC-DC buck regulator, and integrated surge protection, combined with low power dissipation and small packages) optimizes the MAX22514 for use in many different industrial and IO-Link small sensor applications.
• IO-Link Master Transceivers: The MAX22514 is capable of being used in both IOLink devices and IO-Link master applications. A SPI interface is used for extended configurability and diagnostics, and the transceiver is capable of operating at the COM1, COM2, and COM3 IO-Link data rates. The MAX22514 can be configured to enable the required 5mA pull-down/pull-up current on the C/Q line and generate a wake-up pulse.
