9. Functional Description

9.1. Charge Mode

The SW6008 integrates a switching charger with efficiency is up to 96%. The switching charger

supports 4.2V/4.35V/4.4V/4.5V battery voltage. Its switching frequency is up to 500KHz, so a small

size inductor with inductance of 1.0uH can be used.

The switching charger charges battery in three charge phases: trickle charge(TC), constant current

charge(CC) and constant voltage charge(CV). When battery voltage is lower than 3V, charger enters

into trickle charge while the charge current is small current. When battery voltage rises to 3V, charge

enters into constant current charge while charge current is fast charge current. When battery voltage

rises to target charge voltage, charger enters into constant voltage charge while charge current falls so

as battery voltage stays to target voltage. When charge current falls to termination charge current,

charge cycle completes and charger stops. When battery voltage is lower than recharge threshold,

charger automatically restarts.
