23.3. Charge Circuit

When the Handset is put on the cradle of the Base unit or the optional charger, the power is supplied from and
CHARGE- terminals to charge the battery via R268, R269, R270 or Q212 and D214. The voltage between and
CHARGE- flows 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 Operational charging form.
