Positive Supply Voltage Monitor
Positive Battery Supply Voltage
Battery ground relative to the V
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 V
Negative Battery Supply Voltage
Analog Ground. All input signals and the V
Voltage reference output with very low temperature coefficient. The connected resistor
sets internal circuit bias current.
Digital signal input (3 levels) that defines device status with pin 12.
Digital signal input (3 levels) that defines device status with pin 11.
High precision scaled transversal line current signal.
I
Scaled longitudinal line current signal.
