Description
TIP
A line termination output with current capability up to 100mA (I
s
is the current sourced
from this pin).
Positive Supply Voltage Monitor.
Positive Battery Supply Voltage.
Battery ground relative to the V
S+
and the V
B-
supply voltages.
It is also the reference ground for TIP and RING signals.
Positive Power Supply +5V.
2 wire unbalanced voltage input.
Output voltage without current capability, with the following functions:
- give an image of the total battery voltage scaled by 40 to the low voltage part.
- filter by an external capacitor the noise on .
Negative Battery Supply Voltage.
