DUAL SENSOR INTERFACE
FEATURES
o Dual channel switches, configurable for high-side, low-side
and push-pull operation
o Switches are current limited
o Push-pull operation with tristate function
o Output current of up to 100 mA per channel
o Parallel connection of both channels possible
o Channel 1 can be inverted (antivalent output)
o Wide supply voltage range of 9 to 30 V
o Sensor parameterisation via a feedback channel (up to 30 V)
o Switching converters and regulators for 3.3/5 V voltage
generation
o Error detection with hysteresis with excessive temperature,
overload and low voltage
o Driver shutdown in the event of error
o Error messaging via two open-collector outputs
Rev C2, Page 1/15
APPLICATIONS
o Sensor interface for light barriers
and proximity switches, for
example
