MAX14821
IO-Link Device Transceiver
General Description
The MAX14821 transceiver is suitable for IO-Link®
devices and 24V binary sensors/actuators. All specified
IO-Link data rates are supported. In IO-Link applications,
the transceiver acts as the physical layer interface to
a microcontroller running the data-link layer protocol.
Additional 24V digital inputs and outputs are provided.
Two internal linear regulators generate common sensor
and actuator power requirements: 5V and 3.3V.
On-board C/Q and DO drivers are independently configurable
for push-pull, high-side (PNP), or low-side (NPN) operation.
The device detects the IO-Link C/Q wake-up condition
and generates a wake-up signal on the active-low WU
output. The C/Q and DI inputs have selectable current
loads for use in actuators.
An SPI™ interface allows configuration and monitoring
of the device. Extensive alarm conditions are detected
and communicated through the IRQ output and the SPI
interface. The device features reverse-polarity, short-circuit,
and thermal protection. All power lines are monitored for
undervoltage conditions.
The C/Q and DO drivers are specified for sourcing/sinking
up to 100mA.
The device is available in a 2.5mm x 2.5mm, 25-pin wafer-
level package (WLP) and a 4mm x 4mm, 24-pin TQFN
package. Both are specified over the extended -40NC to
+85NC temperature range.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional opera-
tion of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
Package Thermal Characteristics (Note 1)

Note 1: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer
board. For detailed information on package thermal considerations, refer to www.maximintegrated.com/thermal-tutorial.
