Analog Devices Inc. MAX22516 IO-Link Data Link Controllers
Analog Devices MAX22516 IO-Link Data Link Controllers offer an integrated 24V C/Q transceiver, an auxiliary digital input and output, and DC-DC, 5V, and 3.3V linear regulators within a full-featured IO-link controller. The configured MAX22516 operates the IO-Link transceiver and needs no intervention from the external microcontroller during regular operation. Alternatively, the IO-Link transceiver can be controlled directly using the UART interface (TXEN, TX, and RX) or the serial-peripheral interface (SPI).
The ADI 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, short circuit protected, and feature integrated ±1kV/500Ω surge protection.
The MAX22516 is offered 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.
