ACT2802/ACT2802B/ACT2802C
Input current limit at various resistor curve is shown
in Figure 8.
The ILIM pin voltage is proportional to input current
until input current is limited, as shown in Figure 9.
Battery Fast Charge Current
Battery fast charge current is set by a resistor
connected from ICST pin to AGND as shown in
Figure 10. Figure 11 gives out different fast charge
current with various RICST. The battery fast charge
current is estimated as the following equation:
Boost Output Constant Current
Boost output current is set by a resistor connected
from IOST pin to AGND as shown in Figure 12. The
boost output current is estimated as the following
equation:
Figure 13 gives out boost output current with
various RIOST.
The IOST pin voltage is proportional to output
current until output current is limited, as shown in
Figure 14.
