MAX14819/MAX14819A

Dual IO-Link Master Transceiver with Integrated

Framers and L+ Supply Controllers

General Description

Beneﬁts and Features

● Low-Power Architecture

The MAX14819/MAX14819A low-power, dual-channel,

IO-Link master transceiver with sensor/actuator power-

•ꢀ 1Ωꢀ(typ)ꢀDriverꢀOn-Resistanceꢀ

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.

• 1.9mA (typ) Total Supply Current for 2 Channels

• Current Limiters with 15mV Sense Voltage

● Integrated IO-Link Framer Eliminates Need for

External UARTs

• Integrated Cycle Timer Relieves Microcontroller

from Timing-Critical Tasks

The MAX14819/MAX14819A is configurable to operate

either with external UARTs or using the integrated fram-

ers on the IC.

● High Configurability and Integration Reduce SKUs

• Two Auxiliary Type 1/Type 3 Digital Inputs

• Supports NPN Sensors

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-commu-

nication sequencers also simplify wake-up management.

• Dual 24V Sensor Supply Controllers Include:

• Large Capacitive Load Charge Capability

• 2A and Higher Load Currents

● Integrated Protection Enables Robust Systems

• 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.

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.

• Reverse Current Blocking on L+ and C/Q

• 65V Absolute Max Ratings for TVS Flexibility

• Glitch Filters for Improved Burst Resilience

• -40°C to +125°C Operating Temperature Range

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.

Applications

● IO-Link Master Systems

● IO-Link Gateways
