The TIOL221 transceiver integrates dual low-power
output drivers with active reverse polarity protection. When the device is connected
to an IO-Link master through a three-wire interface, the controller can initiate
communication, and exchange data with the remote node while the TIOL221 acts as a
complete physical layer for the communication. The device also integrates an
auxiliary DI channel.
The device is capable of withstanding up to 1.2kV
(500Ω) of IEC 61000-4-5 surge and features integrated reverse polarity protection.
In addition to the SPI for configurability and expanded diagnostic capability, a
simple pin-programmable interface allows easy interfacing with the controller
circuits. The output current limit can be configured using either an external
resistor or per-configured limits via SPI. TIOL221 can be configured to generate
wake-up pulse, and be used in IO-link master applications. Fault reporting and
internal protection functions are provided for undervoltage, overcurrent and
overtemperature conditions.
