MAX14820：IO-Link Device Transceiver

Industry's Highest C/Q Drive Capability Enables Fast Data Rates for Long Cable Runs

The MAX14820 transceiver is suitable for IO-Link® devices and 24V binary sensors/actuators. All specified IO-Link data rates are supported. In IO-Link applications, the transceiver acts as the physical layer interface to a microcontroller running the data-link layer protocol. Additional 24V digital inputs and outputs are provided. Two internal linear regulators generate common sensor and actuator power requirements: 5V and 3.3V. On-board C/Q and DO drivers are independently configurable for push-pull, high-side (PNP), or low-side (NPN) operation. The device detects the IO-Link C/Q wake-up condition and generates a wake-up signal on the active-low WU output. The C/Q and DI inputs have selectable current loads for use in actuators. An SPI™ interface allows configuration and monitoring of the devices. Extensive alarm conditions are detected and communicated through the active-low IRQ output and the SPI interface. The devices feature reverse-polarity, short-circuit, and thermal protection. All power lines are monitored for undervoltage conditions. The C/Q driver is specified for sinking/sourcing ±300mA. The DO driver is specified for sinking/sourcing ±135mA. The MAX14820 is available in a 4mm x 4mm, 24-pin TQFN package, and is specified over the extended -40°C to +85°C temperature range.
