IMON CHARGING CURRENT MONITOR
Charging current is monitored within the charger section and
a proportional voltage representation of the charging current
is presented at the IMON output pin. The output voltage re-
lationship to the actual charging current is represented in the
following graph and by the equation:
V
IMON(mV) = (2.47 x ICHG(mA))
30058606
Note that this function is not available if there is no input at
CHG_IN or if the charger is off due to the input at CHG_IN
being less than the compliance voltage.
