Key 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.
