FEATURES

DESCRIPTIO

The LTC^®4006 is a complete constant-current/constant-

voltage charger controller for 2-, 3- or 4-cell lithium bat-

teries in a small package using few external components.

with ±0.8% accuracy. Charging current is programmable

withasinglesenseresistorto±4%typicalaccuracy.Charg-

ing current can be monitored as a representative voltage at

the I_MONpin. A timer, programmed by an external resistor,

sets the total charge time or is reset to 25% of total charge

time after C/10 charging current is reached. Charging au-

Detection and AC Adapter Present

Fully discharged cells are automatically trickle charged at

10% of the programmed current until the cell voltage ex-

ceeds 2.5V/cell. Charging terminates if the low-battery

condition persists for more than 25% of the total charge

time.

Notebook Computers

LTC4006 includes a thermistor sensor input that sus-

pends charging if an unsafe temperature condition is

detected and automatically resumes charging when bat-

tery temperature returns to within safe limits.
