ISL9203A, Li-ion/Li Polymer Battery Charger
DATASHEET ISL9203A Li-ion/Li Polymer Battery Charger The ISL9203A is an integrated single-cell Li-ion or Li-polymer battery charger capable of operating with an input voltage as low as 2.4V.
This charger is designed to work with various types of AC adapters.
The ISL9203A operates as a linear charger when the AC adapter is a voltage source.
The battery is charged in a CC/CV (constant current/constant voltage) profile.
The charge current is programmable with an external resistor up to 1.5A.
The
ISL9203A Features
* charge current thermal foldback to guarantee safe operation when the printed circuit board is space limited for thermal dissipation. Additional features include preconditioning of an over-discharged battery and thermally enhanced DFN package. Typical Application Circuit 5V INPUT VIN C1 VB
