Update: 30 September, 2023
The MAX14820 is an ideal choice for IO-Link® devices and 24V binary sensors/actuators, supporting all specified IO-Link data rates. 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 IRQ output and the SPI inter- face. 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 device is available in a 4mm x 4mm, 24-pin TQFN package, and is specified over the extended -40NC to +85NC temperature range. Applications include IO-Link sensors, industrial control, and robotics.
