Functional Block Diagram
Theory of Operation
The ISL9205 is an integrated charger for single-cell Li-ion or
Li-polymer batteries. The ISL9205 is capable of operating in
two operation modes, linear charge mode and pulse charge
mode. The ISL9205 functions as a traditional linear charger
when powered with a voltage source adapter. When
powered with a current-limited adapter, the charger functions
as a pulse charger by fully turning on the pass element and
the power dissipation is hence drastically reduced.
Constant Current Phase
The ISL9205 starts the charge at a constant current (CC)
phase. The charge current is regulated to fast charge the
battery before the final voltage has been reached. The
charge current is programmable with the IREF pin and has
two operation modes: trickle mode and constant current
mode, depending on the battery voltage. When the battery
voltage is lower than 2.8V, the charger operates in trickle
mode where the charge current is set at 10% of the constant
current mode current. The trickle mode is for preconditioning
a deeply discharged battery. Once the battery voltage is
above the typical 2.8V threshold, the constant current (CC)
mode starts. The constant current is programmable between
50mA to 1A.
Constant Voltage Phase
When the battery reaches the final voltage, the ISL9205
switches the operation to a constant voltage (CV) phase.
The output voltage is regulated at the final voltage value.
During the constant voltage phase, the charge current
reduces gradually as the cell voltage rises.
