Theory of Operation The ISL9203 is an integrated charger for single-cell Li-ion or Li-polymer batteries. The ISL9203 functions as a traditional linear charger when powered with a voltage-source adapter. When powered with a current-limited adapter, the charger minimizes the thermal ...
Page 11
When using a current-limited adapter, the thermal situation in the ISL9203 is totally different. Figure 19 shows the typical charge curves when a current-limited adapter is employed. The operation requires the programmed higher REF than the limited ...

Recharge After a charge cycle completes, charging is prohibited until the battery voltage drops to a recharge threshold, V (see Electrical Specifications). Then a new charge cycle starts at point t and ends at point shown in ...

The charger will resume charging after the fault condition is removed. When the IREF is driven by a voltage between 0.38V to 0.5V (typical value), the charge current is limited to 100mA; or when driven to a voltage between ...
