charging process is usually terminated when the charging current reaches a set value or
when a charging timer expires (Chapter 7.9 on page 22).
Figure 6 shows the different phases.
Figure 6.
Typical charge curves in linear mode
The worst case in power dissipation occurs when the device starts the fast-charge phase. In
fact, the battery voltage is at its minimum value. In this case, this is the maximum difference
between the adapter voltage and battery voltage, and the charge current is at its maximum
value.
The power dissipated is given by the following equation:
Equation 1
The higher the adapter voltage is, the higher the power dissipated. The maximum power
dissipated depends on the thermal impedance of the device mounted on board.
