Analog Devices / Maxim Integrated MAX22515 IO-Link Transceiver
Analog Devices Inc. MAX22515 IO-Link Transceiver can operate as an IO-Link device in industrial applications. The MAX22515 features a selectable control interface (pin mode or I2C), two integrated linear regulators, and integrated surge protection for robust communication. The transceiver includes one C/Q input-output channel and one digital input (DI) channel. The device features a flexible control interface. Pin-control logic inputs allow for operation with switching sensors that do not use a microcontroller. For sensors that use a microcontroller, an I2C interface is available, providing extensive configuration and diagnostics. Additionally, an integrated oscillator simplifies the clock generation for IO-Link devices.
The MAX22515 features extensive integrated protection to ensure robust communication in harsh industrial environments. All IO-Link line interface pins (V24, C/Q, DI, and GND) are reverse voltage protected, short-circuit protected, hot-plug protected, and feature integrated ±1.2kV/500Ω surge protection. The Analog Devices Inc. MAX22515 IO-Link Transceiver is available in a tiny WLP package (2.5mm x 2.0mm) or a 24-pin TQFN-EP package (4mm x 4mm) and operates over the -40ºC to +125ºC temperature range.
