Analog Devices / Maxim Integrated MAX14819/A Dual IO-Link Master Transceivers
Analog Devices MAX14819/A Dual IO-Link® Master Transceivers come with sensor/actuator power-supply controllers and are fully compliant with the current IO-Link. These devices are compliant with 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/A is configurable to operate either with external UARTs or using the integrated framers on the IC.
To ease the selection of microcontrollers, the master transceiver features frame handlers with UARTs and FIFOs. This feature is designed to simplify time-critical control of all IO-Link M-sequence frame types. The MAX14819/A 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/A 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/A is available in a 48-pin (7mm x 7mm) TQFN package and is specified over the extended -40°C to +125°C temperature range.
