3.3.2. Charging
SM-POWER provides together with an external p-channel FET Siliconix Si3455 an external AC-
adapter a complete charge control function for charging of Li-Ion or Li-Ion-Polymer batteries. Either
a 1-cell Li-Ion or Li-Ion-Polymer battery with 4.1, 4.2 or 4.4 Volts may be used.
1. Charging method : CC-CV
2. Charger detect voltage : 4.0V
3. Charging time : 3h
4. Charging current : 500mA
5. CV voltage : 4.2V
6. Cutoff current : 100mA
7. Full charge indication current (icon stop current) : 100mA
8. Recharge voltage : 4.00V
9. Low battery alarm
a. Idle : 3.50V~3.35V
b. Dedicated : 3.59V~3.35V
10. Low battery alarm interval
a. Idle : 3min
b. Dedicated:1min
11. Switch-off voltage : 3.35V
12. Charging temperature adc range
a. ~ -5˚C : low charging voltage operation (3.6V ~ 3.9V) .
b. -5˚C ~ 50˚C : standard charging (up to 4.2 V)
c. 50˚C ~ : low charging voltage operation (3.6V ~ 3.9V)
