General Description

The MAX22516 IO-Link data link controller integrates a

24V C/Q transceiver, an auxiliary digital input and

output, an integrated DC-DC, 5V and 3.3V linear

regulators, and a full-feature IO-Link data link controller.

Once configured, the MAX22516 data link controller

operates the IO-Link transceiver and requires no

intervention from the external microcontroller during

normal operation. Alternatively, the IO-Link transceiver

can be controlled using the UART interface (TXEN, TX,

and RX) directly, or through the serial-peripheral

interface (SPI). The data link controller supports and

includes, receive and transmit buffers for IO-link

communication. Buffers for maximum size process data,

ISDU, event, and page data reduce the need for timecritical

microcontroller intervention, which allows the

microcontroller to focus on the application layer task.

The MAX22516 features extensive integrated protection

to ensure robust communication in harsh industrial

environments. All IO-Link interface pins (V24, C/Q, DO,

DI, and GND), are reverse voltage protected, shortcircuit

protected, and feature integrated ±1kV/500Ω

surge protection.

The MAX22516 is available in a tiny WLP package

(3.53mm x 3.16mm) or 40-pin TQFN-EP package (5mm

x 5mm) and operates over the -40°C to +125°C

temperature range.
