Name

Description

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.
