Description

The MAX14819/MAX14819A 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 1.1.3. This master transceiver also includes two auxiliary digital input (DI_) channels.

The MAX14819/MAX14819A is configurable to operate either with external UARTs or using the integrated fram- ers 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/MAX14819A also features autonomous cycle timers, reducing the need for accurate controller timing. Integrated establish-communication sequencers also simplify wake-up management.

The device message response delay on the MAX14819A can be disabled when using the frame handler and the MAX14819A features higher L+ thresholds than the MAX14819. The MAX14819A receivers also feature increased high-frequency signal isolation compared to the MAX14819.

The MAX14819/MAX14819A 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.

The MAX14819/MAX14819A is available in a 48-pin (7mm x 7mm) TQFN package and is specified over the extended -40°C to +125°C temperature range.
