MAX14819AATM+T

Drivers, Receivers, Transceivers Overview

The MAX14819AATM+T is a dual-channel IO-Link master transceiver with integrated framers and L+ supply controllers. It operates within a VCC range of 9V to 36V and supports VL logic levels from 1.62V to 5.5V. The device features two auxiliary digital inputs and autonomous cycle timers. Supply current is typically 0.75mA at VCC and 1.9mA at V5. Driver on-resistance is 1Ω typical. It includes reverse polarity protection, overvoltage tolerance up to 65V, and thermal shutdown at +160°C. Operating temperature spans -40°C to +125°C in a 48-pin TQFN package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated IO-Link framer eliminates the need for external UARTs
• Dual low-power sensor supply controllers with advanced current limiting
• Autonomous cycle timers reduce microcontroller timing requirements
• High-voltage tolerant interface pins with reverse polarity protection

Drivers, Receivers, Transceivers Applications

• IO-Link Master Systems
• IO-Link Gateways

Drivers, Receivers, Transceivers Procurement Notes

Verify the 'A' suffix indicates higher L+ thresholds and increased high-frequency signal isolation compared to the standard MAX14819. Confirm the 'TM+' suffix corresponds to the 48-TQFN (7mm x 7mm) RoHS-compliant package. Ensure the 'T' suffix denotes tape-and-reel packaging if required by assembly equipment. Cross-reference the specific revision against the manufacturer's latest datasheet to confirm pinout and electrical characteristics.

Drivers, Receivers, Transceivers Selection Notes

Select this component when an IO-Link master requires integrated framing and power management in a compact form factor. The MAX14819A variant offers superior high-frequency signal isolation and higher L+ thresholds compared to the base MAX14819 model. Consider the integrated frame handlers and FIFOs if minimizing external MCU complexity is a priority. Verify that the 48-pin TQFN footprint fits the PCB layout constraints.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX14819 series of dual-channel IO-Link master transceivers. It is designed to simplify the implementation of IO-Link master nodes by combining transceiver, framer, and power controller functions into a single IC. The series supports IEC 61131-2 and IO-Link 1.1.3 standards.

Drivers, Receivers, Transceivers Replacement Considerations

MAX14819ATM+T is the non-tape-and-reel tray version of the same functional device. MAX14819 variants lack the enhanced isolation and L+ threshold improvements found in the MAX14819A.
