bq2056/T/V  
Low-Dropout Li-Ion Charge-Control ICs with  
AutoComp™ Charge-Rate Compensation  
automatic charge-rate compensation  
General Description  
Features  
(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.  
Significant reduction in charge  
time with AutoComp charge-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  
Ideal for low-dropout linear regu-  
lator design  
1-cell, 2-cell, and programmable  
multicell versions  
Low-cost charger implementation

nal components
