MAX14819AATM+

MAX14819AATM+ is a low-power, dual-channel, IO-Link® host transceiver with sensor/actuator power supply controllers that are 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 host transceiver also includes two auxiliary digital input (DI-) channels. It is configurable to operate either with external UARTs or using the integrated framers on the IC. It also 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. It is used in applications such as IO-link host systems, and IO-link gateways.

• Integrated cycle timer relieves microcontroller from timing-critical tasks
• High configurability and integration reduce SKUs
• Reverse polarity protection on all interface pins, overvoltage tolerance on all interface pins
• C/Q and DI fully compliant with IEC 61131-2, C/Q compliant with IO-link 1.1.3
• Reverse current blocking on L+ and C/Q, 65V absolute max ratings for TVS flexibility
• Glitch filters for improved burst resilience, VCC supply voltage range from 9V to 36V
• VCC supply current is 0.4mA typical at (VCC = 9V to 36V, V5 = 4.5V to 5.5V)
• Driver on-resistance is 1 ohm typical at (high-side enabled, ILOAD = -200mA)
• External clock frequency is 3.686MHz typical at (VCC = 9V to 36V, V5 = 4.5V to 5.5V)
• Operating temperature range from -40°C to +125°C, 48-pin TQFN-EP package
