MAX14819ATM+

MAX14819ATM+ is a low-power, dual-channel, IO-Link® host transceiver with integrated framers and L+ supply controllers. It 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. It is configurable to operate either with external UARTs or using the integrated framers on the IC. To ease the selection of a microcontroller, the host transceiver features frame handlers with UARTs and FIFOs. It is designed to simplify time-critical control of all IO-Link M-sequence frame types. It features autonomous cycle timers, reducing the need for accurate controller timing. Integrated establish-communication sequencers also simplify wake-up management. It 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. Applications include IO-link host systems, IO-link gateways.

• Includes two auxiliary digital input (DI-) channels
