UB2011, CHARGE MANAGEMENT

UNISONIC TECHNOLOGIES CO., LTD UB2011 Preliminary ADVANCED LINEAR AND SWITCH MODE CHARGE MANAGEMENT IC FOR LITHIUM-ION AND LITHIUM-POLYMER * D

Features

* Ideal for 1-4 Series Circuit Cell Li-Ion or Li-Pol Packs
* High Accuracy of Voltage Regulation With Preset Voltages
* Optional Cell-Temperature Monitoring
* Current Regulation With Programmable Charge-Current
* Charge Termination by Minimum Current
* With Short-Circuit Prot

Applications

* the battery temperature is continuously under monitor by using an external thermistor, if the temperature is over user-defined threshold; UTC UB2011 inhibits charge for safety concern. UTC UB2011 charges the battery in conditioning, constant voltage and constant current phases. If the battery volta
