TYPICAL APPLICATIONS
Table 6. RICHG Values for Some Desired ICHG Values
Figure 20. External Resistor (RICHG) Value Versus
Charging Current Limit Value (ICHG)
Choosing the External Capacitor CICHG Value
The user can also change the charging current rise time by
adding a capacitor (CICHG) between the ICHG and VIN pins,
as shown in Figure 19, page 17. The charging current rise
time ranges between 1.0 ms (default value) and a
recommended maximum of 10 ms. Table 7 lists examples of
CICHG for different values of tICHGR and Figure 21 shows a
plot of CICHG versus tICHGR.
To calculate the value of the CICHG capacitor we use the
following equation:
CICHG(nF) = 1000 * tICHGR(ms) / [3 * RICHG(kΩ)]
