MAXREFDES145#: 8-Channel IO-Link Master

The MAXREFDES145# 8-Channel IO-Link® Master Quick Start Guide describes the steps required to quickly get the MAXREFDES145# reference design up and running by controlling it with TEConcept's Control Tool IO-Link master software.

The MAX14819 low-power, dual-channel, IO-Link® master transceiver with sensor/actuator power-supply controllers is fully compliant with the latest IO-Link and binary input standards and test specifications, IEC 61131-2, IEC 61131-9 SDCI, and IO-Link 1.1.2. This master transceiver also includes two auxiliary digital input (DI_) channels.

The MAX14819 is configurable to operate either with external UARTs or using the integrated framers on the IC. To ease selection of microcontroller, the master transceiver features frame handlers with UARTs and FIFOs. These are designed to simplify time critical control of all IO-Link M-sequence frame types.

The MAX14819 also features autonomous cycle timers, reducing the need for accurate controller timing. Integrated establish-communication sequencers also simplify wake-up management.

The MAX14819 integrates two low-power sensor supply controllers with advanced current limiting, reverse current blocking, and reverse polarity protection capability to enable low-power robust solutions.
