6.14.5.8. Charge Circuit
When the Handset is put on the cradle of the Base unit or the charger, the power is supplied from CHARGE+ and CHARGE- ter-
minals to charge the battery via R368 or Q361, and D361. The voltage between CHARGE+ and CHARGE- flows R231 → Q231
→ pin38 of IC201, where the charge is detected. Then IC201 calculates the battery consumption amount from the previous
charge, and it controls Q361/Q362/Q363 by pin80 of IC201 until charging is complete. When charging is complete, the control
pattern is switched to Trickle charging form from Operational charging form.
