When used as a digital input, a series 33 kΩ resistor must be used to protect against automotive transients.
Reverse battery protection series diodes must be used externally to protect the internal circuitry.
This pin can be connected directly to the battery line for voltage measurements. The pin is self-protected against reverse battery
connections. It is strongly recommended to connect a 10 kΩ resistor in series with this pin for protection purposes.
External capacitor (2.0 µF < C < 100 µF; 0.1Ω < ESR < 10 Ω) required.

Output
This input pin is for configuration of the watchdog period and
allows the disabling of the watchdog.
This pin represents the single-wire bus transmitter and receiver.
This pin is the device LIN ground connection. It is internally connected to the
PGND pin.
Relay drivers low side outputs.
This pin is the device low side ground connection. It is internally connected to
the LGND pin.
These pins are the wake-up capable digital inputs
can be sensed analog via the analog multiplexer.
High side switch output.
These pins are device battery level power supply pins. VS2 is supplying the
HS1 driver while VS1 supplies the remaining blocks.
Battery voltage sense input.
