UB2012, ADVANCED LINEAR CHARGE MANAGEMENT

UNISONIC TECHNOLOGIES CO., LTD UB2012 LINEAR INTEGRATED CIRCUIT ADVANCED LINEAR CHARGE MANAGEMENT IC FOR SINGLE AND TWO-CELL LITHIUM-ION AND LITHIU.
UTC UB2012 is designed for portable electronics with lower cost.

Features

* Ideal for Single 4.1V,4.2V and Dual-Cell 8.2V,8.4V Li-Ion or Li-Pol Packs
* 0.3V Dropout Voltage for Minimizing Heat Dissipation
* Better than ±1.2% Accuracy of Voltage Regulation With Preset Voltages
* Dynamic Compensation of Battery Pack’s Internal Impedance to short Charging Tim

Applications

* the battery temperature is continuously under monitor by using an external thermistor, if the temperature is over user-defined threshold; UTC UB2012 inhibits charge for safety concern. Generally, the UTC UB2012 charges the battery in conditioning, constant voltage and constant current phases. I
