compares this current against the desired current programmed
by R IMON at the I MON pin and adjusts I TH until:
V REF V – V + 11 . 67 μ A ? 3 k ?
R IMON 3 k ?
therefore,
? V ? 3 k ?
? R IMON ? R SENSE
The voltage at BAT is divided down by an internal resistor
divider and is used by error amp EA to decrease I TH if the
divider voltage is above the 1.19V reference. When the
charging current begins to decrease, the voltage at I MON

Note 1: If a depleted battery is inserted while the charger is in this state,
the charger must be reset to initiate charging.
The accuracy of V IMON will range from 0% to I TOL .
V IMON is plotted in Figure 2.
The amplifier CL1 monitors and limits the input current to
a preset level (100mV/R CL ). At input current limit, CL1 will
decrease the I TH voltage, thereby reducing charging cur-
rent. When this condition is detected, the C/10 indicator will
