Analog Integrated Circuit Device Data
Output of the safe circuitry. The pin is
asserted LOW if a fault event occurs
(e.g.: software watchdog is not
triggered, V
pin, etc.). Open drain structure.
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
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
measurements.
Configurable pin as an input or
output, for connection to external
circuitry (switched or small load). The
voltage level can be read by the SPI
and via the MUX output pin. The
input can be used as a
programmable Wake-up input in LP
mode. In LP, when used as an
output, the High Side (HS) or Low
Side (LS) can be activated for a cyclic
sense function.
Input to activate the Debug mode. In
Debug mode, no watchdog refresh is
necessary. Outside of Debug mode,
connection of a resistor between
DBG and GND allows the selection of
Safe mode functionality.
LIN bus transmit data input. Includes
an internal pull-up resistor to VDD.
Ground of the IC.
LIN bus receive data output.
