MAX14824
IO-Link Master Transceiver
General Description
The MAX14824 is an IO-LinkM master interface that inte-
grates an IO-Link physical layer transceiver with an
auxiliary digital input and two linear regulators. High port
count IO-Link master applications are supported through
in-band SPI addressing, and the 12MHz SPI interface
minimizes host controller access times. In-band address-
ing and selectable SPI addresses enable cascading up
to 16 devices.
The device supports all the IO-Link data rates and fea-
tures slew-rate-controlled drivers to reduce EMI. The
driver is guaranteed to drive up to 300mA (min) load
currents. Internal wake-up circuitry automatically deter-
mines the correct wake-up polarity, allowing for the use
of simple UARTs for wake-up pulse generation.
The MAX14824 is available in a 4mm x 4mm, 24-pin
TQFN package with exposed pad, and operates over the
extended -40NC to +105NC 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.

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.maxim-ic.com/thermal-tutorial.
