Power-on circuitry,2. Voltage regulators,3. Battery charging circuitry,4. Power fail detection.In order to reduce the size and weight of the phone, two Li-ION cells have been chosen as the main power source.To reduce the cost of the phone four Ni-MH cells can be used as the optional power source. The Li-ION standardbattery gives 400mAH (typical) capacity. The optional Ni_MH battery gives 670mAH capacity.Battery operating voltage range:4.5V (minimum safe discharge)6V (maximum fully charged Ni-MH)8.2V (maximum fully charged Li-ION)The G600 battery management operates with the following voltage levels:Battery Voltage Li-ION Ni-MHB-Icon 3 bar 7.55< 4.90<B-Icon 2 bar 7.20< <7.55 4.75< <4.90B-Icon 1 bar 6.00< <7.20 4.50< <4.75LVA <6.00 <4.50Issue 1 Section 9 MCUK980101G8Revision 0 9 - 4 Technical GuidePOWER SUPPLIES
