TRANSCEIVER
FEATURES
o IO-Link compliant slave transceiver
o Dual channel switches, configurable for high-side, low-side
and push-pull operation with tristate function
o Configuration via pins or SPI interface
o Switches are current limited
o Switches, iC supply and feedback channel are protected
against reverse polarity
o Output current of up to 150 mA per channel
o Parallel connection of both channels possible
o The channels can be inverted for antivalent output
o Sensor communication request function (IO-Link wake-up)
o Wide supply voltage range of 9 to 30 V
o Sensor parametrisation via a feedback channel (up to 30 V)
o Switching converters and linear regulators for 3.3/5 V voltage
generation
o Error detection with hysteresis with excess temperature,
overload and undervoltage
o Driver shut-down on all errors
o Error signalling at two open-collector outputs
Rev C1, Page 1/26
APPLICATIONS
