FUNCTIONS OF CLA
¥ Protection Circuit
Protection Circuit is the circuit against the
electrical stress which is occured at unexpected
conditions of the source power of CLA unit such
as reverse voltage or overcurrent.
¥ Detection of DBDM phone
If cellular phone is connected to CLA, the CLA
lamp is on to display whether charge will be done
normally or not.
¥ Detect Carrier-On
In the case of Carrier-On, CLA detects the
resistance of the Cellular Phone and reduces the
charge current.
¥ Detect Full-Charge
If the temperature of the battery pack is higher
than the temperature outside of the cellular
phone, CLA detects the battery fully charged and
the state will be converted to the Trickle Charge.
