VOLTAGE SENSE PIN (VSENSE)
is protected against battery reverse connection. The voltage
present in this input is scaled down by an internal voltage
divider, and can be routed to the ADOUT0 output pin and
used by the MCU to read the battery voltage.
+40 V and down to -27 V, allowing this pin to be connected
directly to the battery line. It is strongly recommended to
connect a 10 kohm resistor in series with this pin for
protection purposes.
