MAX22514AWA+

MAX22514AWA+ is a surge-protected IO-link transceiver with DC-DC. It 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 device for use in many different industrial and IO-Link small sensor applications. It is capable of being used in both IO-Link devices and IO-Link host applications. An 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. It can be configured to enable the required 5mA pull-down/pull-up current on the C/Q line and generate a wake-up pulse.
