7.4
Connecting SI_ENABLE to 5V causes SI_GND to have low impedance. Thus the SI
comparator is in operation and can be used to monitor the battery voltage. SO output
signal is valid. Connecting SI_ENABLE to GND causes SI_GND to have high
impedance. Thus the SI comparator is not able to monitor the battery voltage. SO output
signal is invalid.
7.5
The formula to calculate the resistor divider for the sense comparator is basically the
same as for the feedback divider in section before. With the selected resistor R
desired threshold of the input voltage V
resistor R
For high accuracy and low ohmic resistor divider values the On-resistance of the
SI_GND NMOS (typ. 100 ) has to be added to R
