MAX14820
IO-Link Device Transceiver
19-5787; Rev 6; 3/14
General Description
The MAX14820 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 devices. Extensive alarm conditions are detected and
communicated through the IRQ output and the SPI inter-
face. The devices feature reverse-polarity, short-circuit,
and thermal protection. All power lines are monitored for
undervoltage conditions.
The C/Q driver is specified for sinking/sourcing 300mA.
The DO driver is specified for sinking/sourcing 135mA.
The device is available in a 4mm x 4mm, 24-pin TQFN
package, and is specified over the extended -40NC to
+85NC temperature range.
