3.5 Charger
•
Controlled by KB926 microprocessor from motherboard
•
Temperature sense capability for the battery (charge active between 0°C~
40°C)
•
Fast charge current 3Amps (max.) for Li-Ion Battery at system off, approach
25W fast charge at system ON. (Depend on system load)
•
Trickle charge: Typical 600mA pre-charge current for Li-Ion Battery. All
trickle charge are controlled by KB926.
•
Charge termination: When Fully-Charge bit is set, charger is terminated by
KB926
•
When system is turned off, the charge time is 4.0 hrs typically from empty to
full for Li-Ion 9 cell battery. When system is turned off, the charge time is
3.5 hrs typically from empty to full for Li-Ion6 cell battery.
