33905D, Output pin for the LIN2 master node termination
resistor.
or
33904A/33905S, Configurable pin as an input or high side
output, for connection to external circuitry (switched or small
load). The input can be used as a programmable wake-up
input in Low Power mode. When used as a high side, no over-
temperature protection is implemented. A basic short to GND
protection function, based on switch drain-source over-
voltage detection, is available.
33905D, Output pin for the LIN1 master node termination
resistor.
or
33905S, 33905D, Configurable pin as an input or high side
output, for connection to external circuitry (switched or small
load). The input can be used as a programmable wake-up
input in Low Power mode. When used as a high side, no over-
temperature protection is implemented. A basic short to GND
protection function, based on switch drain-source over-
voltage detection, is available.
33904, Configurable terminal as input or high side output, for
connection to external circuitry (switched or small load). Input
can be used as a programmable wake-up input from Low
Power Mode. When used as high side, no over-temperature
protection is implemented. A basic short to GND protection
function based on switch drain-source over-voltage detection
is available.
Output of the safe circuitry. The pin is asserted LOW in case
of a safe condition is detected (e.g.: software watchdog is not
triggered, V

Output voltage for the embedded CAN interface. A capacitor
must be connected to this pin.
CAN high output.
CAN low output.
Power GND of the embedded CAN interface
Output pin for connection to the middle point of the split CAN
termination
Output pin for external path PNP transistor base
Output pin for external path PNP transistor collector
Output pin for the auxiliary voltage.
Multiplexed output to be connected to an MCU A/D input.
Selection of the analog parameter available at MUX-OUT is
done via the SPI. A switchable internal pull-down resistor is
integrated for V
