1.2.5System Clock.
The system clock for the telephone is 13 MHz TCXO, generated by X600. It is processed in IC300 to provide serial clock for LCD, EEPROM, and IC100. The clock is buffered in IC300 One-C, and then fed to IC100 IPD as “CPU CLK ” . It is available on pin 56 of IC100.
During Stand-By mode, the system clock is not managed from X600 TCXO but from X300 ( “slow clock ” at 32.768 kHz).

2.2 Description.
The battery is NiMH 900mAh, 3.8 V nominal for Galaxy, Astral and Geo
External power supply for charging (EXPS) comes from the DC jack at the bottom side of the mobile (AC/DC, CLA, DTC or H/F Kit). This power supply is 5.8 V nominal. Battery presence and battery type information are accessible in CHGM IPD register. If a Li-ion battery is detect, the software considers that the battery is absent.
The battery temperature information (TH) is given by thresholds in IPD CHGM register. This information are used only for charge control.
The battery level information is accessible in an A/D converter in One-C. It is also available in CHGM IPD register , these information are given by range only for range control.
External power supply (EXPS) presence information are accessible in CHGD IPD register. As described in the drawing above, the power supply for Base Band (IC300) comes from EXPS when it is present because EXPS level (5.8 V) is always greater than battery voltage. On the contrary, power supply for radio always comes from the battery.
The serial diode between battery and One-C (IC300) can be bypassed by software to reduce voltage headroom. Bypass is Activated when battery is less than 3.45 V.

2.3 Charging process.
Charging process follows these successive phases :
Pre charge :This phase is mandatory before the rapid charge to verify that battery operation is normal (normal battery voltage and temperature). Charge current during this phase is 52 mA. If the battery voltage is higher than 3.3 Volts, the S/W launch IPD charger in rapid charge except if the temperature is not between 0°C and 55°C.
2) Rapid charge : Charge current during this phase is 420mA. If battery temperature becomes abnormal IPD charger start at low current charge (21 mA), while temperature comes back normal (between 0°C and +55°C) during 15 mn. Full charge detection ends Rapid charge. Full charge is detected by S/W when charge current decreases under 50 mA (full charge convergence current).
3) Trickle mode :This phase is necessary to complete the charge and to avoid battery auto discharge. Charge current during this phase is 21 mA. Trickle charge is automatically stopped after 24 hours duration.

2.4Main characteristics.
The phone transmits only if the battery is attached to it, in any configuration of power supply. When the phone is connected to H/F adapter, DTC, AC/DC, or CLA, the battery charging circuit operates. Battery voltage (+3.8 V) is applied via D118 or from TESTPS ( J103 pin1 ) through D124 when using Hand Free.
The main power supply is fed to the phone either from the attached battery via the connector J101, or from accessories :
∙H/F adapter,
∙Desk Top Charger DTC,
∙AC/DC adapter and CLA via the external connector J103.
R120 and R121 give an internal voltage reference. If the battery voltage VBAT falls down, then BYPASS shorts out the diode D118 through TR103 to reduce voltage drop.
2.5Autonomy Control.
The battery energy is displayed on the LCD by a 3 bars “battery icon” . Voltage thresholds for each bars are calculated to have this autonomy time share out:
0% |
40% |
80% |
97% |
100% |

A 3 times 33% time shares out is not possible because of the very stable battery level between 20% to 50% autonomy time. In addition with these bars, a ” low battery alarm” is displayed between ”1 bar” and the mobile off.
All these thresholds are programmed in EEprom by the factory and given in following thresholds table.

Thresholds are different according to the mode, Idle mode or Call mode. Idle mode threshold are checked by software 25 min after the end of the call.
When battery voltage is less than the threshold given in the table above, BAT_EMPTY is true.

During these mode TESTPS and EXPS = low voltage level.
A high voltage level on MUPSU implies regulators REG 4, REG 5, REG 6, REG 7 are active.

When you connect I/O connector, MUPSU and BBPWR signals have the same waveform at TESTPS.
During this condition PWRKEY and EXPS = low voltage level.
- With AC/DC Charger, Cigar Light Adapter and DeskTop Charger.
