BQ2056T General Description

The bq2056 series ICs are low-cost precision linear charge-control devices for Li-Ion batteries. With a minimum number of external components, 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 external PNP transistor or P-channel FET. Features include proprietaryautomatic charge-rate compensation (AutoComp) and a trickle-charger interface output for reviving deeply discharged cells. The bq2056 supports a single-cell 4.1V pack and the 2056T supports a two-cell 8.2V pack.The bq2056V may be externally programmed for supporting other voltages. All versions feature a sleep modeforlow-powerapplications.
