19.3. Charge Circuit
When the handset is put on the cradle of the Base unit or charger, the power is supplied from CHARGE2 and CHARGE1
terminals to charge the battery via D205 (D207), R268, Q212. The voltage between CHARGE2 and CHARGE1 flows D213 ->
R248 -> Q207 -> pin80 of IC201, where the charge is detected. Then IC201 calculates the battery consumption amount from
the previous charge, and it controls Q212/Q210/Q209 by pin82 of IC201 until charging is complete. When charging is complete,
the control pattern is switched to Trickle charging form from Normal charging form.
