The MAX14826 transceiver is suitable for IO-Link® devices and 24V binary sensors. 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/THSD output.
The MAX14826 includes a selectable parallel or SPI interface for configuration and monitoring of the drivers. Extensive alarm conditions are detected and communicated through the interrupt outputs and the SPI interface. The device features reverse-polarity, short-circuit, and thermal protection. All power lines are monitored for undervoltage conditions.
The C/Q and DO drivers are specified for sinking/sourcing 200mA.
The MAX14826 is available in a 4mm x 4mm, 24-pin TQFN package, and is specified over the extended -40°C to +105°C temperature range.
