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
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 Low Power
mode. In low power, when used as an output, the
high side or low side 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.
LIN bus input output connected to the LIN bus.
LIN bus input output connected to the LIN bus.
LIN bus transmit data input. Includes an internal
pull-up resistor to VDD.
LIN bus receive data output.
Direct battery voltage input sense. A serial resistor
is required to limit the input current during high
voltage transients.
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 Low Power
mode. Can be used in association with I/O-0 for a
cyclic sense function in Low Power mode.
This is the device reset output whose main
function is to reset the MCU. This pin has an
internal pull-up to VDD
also monitored in order to detect external reset
and safe conditions.
