TRANSCEIVER
Rev C1, Page 1/26
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
