Low-Dropout Li-Ion Charge-Control ICs With AutoComp?⠃harge-Rate Compensation

The BQ2056 series ICs are low-cost precision linear charge-control de- vices for Li-Ion batteries. With a minimum number of external compo- nents, the BQ2056 is a complete low- dropout linear charger. The dropout voltage is typically less than 0.5V when the BQ2056 is used with an ex- ternal PNP Transistor or P-channel FET Features include proprietary Automatic charge-rate compensation (AutoComp) and a trickle-charger in- terface output for reviving deeply discharged cells. The BQ2056 sup- ports a single-cell 4.1V pack and the 2056T supports a two-cell 8.2V pack. The bq2056V may be externally pro- grammed for supporting other volt- ages. All versions feature a sleep mode for low-power applications By Texas Instruments
