Pre-charge Mode
This mode is automatically enabled when the battery
voltage is below the pre-charge threshold voltage (VT PreQ ),
typically 2.9V. Pre-charge current conditions the battery
for fast charging. The pre-charge current value is fixed at
20% nominally of the fast-charge current for the selected
input, as programmed by the resistance between IPRGM
and GND.
Pre-charge current regulation accuracy is dominated by
offset error. The range of expected pre-charge output

Figure 1b — Fast-charge Current Tolerance versus
Programming Resistance, High Resistance Range
current versus programming resistance is shown in
Figures 2a and 2b. The figures show the nominal pre-
charge current versus nominal R IPRGM resistance as the
center plot and two theoretical limit plots indicating
maximum and minimum current versus nominal pro-
gramming resistance. These plots are derived from
models of the expected worst-case contribution of error
sources depending on programmed current. The current
range includes the uncertainty due to 1% tolerance resis-
tors. The dots on each plot indicate the currents obtained
with the EIA E96 standard value 1% tolerance resistors.
