9. Functional Description
9.1 Charge Mode
The SW6124 integrates a switching charger with charge current up to 4A and efficiency is up to 96%. The
switching charger supports 4.2V/4.3V/4.35V/4.4V battery voltage. Its switching frequency is up to 400KHz, so
a small size inductor with inductance of 2.2uH 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 200mA when battery voltage is lower than 1.5V and 300mA when battery voltage is
between 1.5V and 3.0V. 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.
