Charge Circuit; Ringer And Handset Sp-Phone - Panasonic KX-TG2343F Service Manual

17.3. Charge Circuit

When the handset is put on the cradle of the Base unit or the optional 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.
