GLOSSARY
VICM Output Voltage of Input Current Monitor
ICREF Input Current Reference - sets the threshold for the input current limit
DPM Dynamic Power Management
CSOP, CSON Current Sense Output of battery positive and negative
These pins are used with an external low-value series resistor to monitor the current to and
from the battery pack.
CSSP, CSSN Current Sense Supply positive and negative
These pins are used with an external low-value series resistor to monitor the current from
the adapter supply.
