MAX14826 IO-Link Device Transceiver General Description Benefits and Features The MAX14826 transceiver is suitable for IO-Link IO-Link Specification v.1.0 and v.1.1 Physical Layer devices and 24V binary sensors. All specified IO-Link Compliant data rates are supported. In IO-Link applications, the High Configurability and Integration Reduce SKUs transceiver acts as the physical layer interface to a Push-Pull, High-Side, or Low-Side Outputs microcontroller running the data-link layer protocol. Supports COM1, COM2, and COM3 Data Rates Additional 24V digital inputs and outputs are provided. SPI or Pin-Driven Control and Monitoring Two internal linear regulators generate common sensor and actuator power requirements: 5V and 3.3V. 2.5V to 5V Logic Interface Levels C/Q and DO Drivers Can Be Connected in Parallel On-board C/Q and DO drivers are independently- configurable for push-pull, high-side (PNP), or low-side Auxiliary 24V, 200mA Digital Output (DO) (NPN) operation. The device detects the IO-Link C/Q Auxiliary 24V Digital Input (DI) wake-up condition and generates a wake-up signal on the Integrated 5V and 3.3V Linear Regulators active-low WU/THSD output. Driver Currents Specified for 200mA, 100mA The MAX14826 includes a selectable parallel or SPI and 50mA interface for configuration and monitoring of the drivers. 1F C/Q and DO Load Drive Capability Extensive alarm conditions are detected and communicated Integrated Protection Enables Robust Solutions through the interrupt outputs and the SPI interface. The Extensive Fault-Monitoring and Reporting device features reverse-polarity, short-circuit, and thermal Reverse-Polarity and Short-Circuit Protection on All protection. All power lines are monitored for undervoltage 24V Inputs/Outputs conditions. Reverse-Polarity Protected 24V Supply Output The C/Q and DO drivers are specified for sinking/sourcing -40C to +105C Operating Temperature Range 200mA. The MAX14826 is available in a 4mm x 4mm, 24-pin Backwards Pin-and Software-Compatible to TQFN package, and is specified over the extended -40C MAX14821 to +105C temperature range.
