CSMC 0.13um 5v-3.3v/1.2v Battery Charger
Based on CSMC 0.13um 3.3V/1.2V Logic process, current design of the Battery Charger IP is a complete constant current/constant voltage linear charger for single cell lithium-ion and lithium-polymer battery designed to work within the USB power specification. It presets 4.2V Charge Voltage with ±1% Accuracy. The Battery Charger IP terminates the charging process when the charge current drops by 10% after the final float voltage is reached.
Due to the internal MOSFET architecture, no external sense resistor or external blocking diode is required. The thermal feedback regulates the charge current to limit the die temperature during high power operation or high ambient temperature conditions.
