MAX14821
IO-Link Device Transceiver
19-5916; Rev 3; 3/14
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 applica-
tions, 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 config-
urable 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 inter-
face. 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/sink-
ing up to 100mA.
The device is available in a 2.5mm x 2.5mm, 25-pin WLP
and a 4mm x 4mm, 24-pin TQFN package. Both are speci-
fied over the extended -40NC to +85NC temperature range.
