Table 7. Variables Description
Variable
Name
Description
VX
The voltage on Pin X
VRS
The regulation setpoint for the voltage across the
sense resistor (RS)
VBAT, EOC
The battery voltage at the point charging current is
1/10 the current setpoint
IMAX
The charge current corresponding to VRS,
including the effects of ADJ pin voltage
IMAX0
The charge current corresponding to the VRS
setpoint, ignoring ADJ effects (i.e. C0 = 150 mV/RS)
C rate
The charge current (mA) expressed as a multiple of
the nominal battery capacity (mAh). A 900 mAh
capacity battery charged at a 1/10 C rate, is
equivalent to a 90 mA charge current.
