16-Pin Narrow SSOP Package
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.
The PWM controller is a synchronous, quasi-constant fre-
quency, constant off-time architecture that will not gener-
ate audible noise even when using ceramic capacitors.
The LTC4006 is available in 8.4V, 12.6V and 16.8V versions
with ± 0.8% voltage accuracy. Charging current is program-
mable with a single sense resistor to ± 4% typical accuracy.
Charging current can be monitored as a representative
voltage at the I MON pin. 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. Charg-
ing automatically resumes when the cell voltage falls below
3.9V/cell.
Fully discharged cells are automatically trickle charged at
10% of the programmed current until the cell voltage ex-
APPLICATIO S
ceeds 2.5V/cell. Charging terminates if the low-battery
condition persists for more than 25% of the total charge

time.
The LTC4006 includes a thermistor sensor input that
suspends charging if an unsafe temperature condition is
detected and automatically resumes charging when the
battery temperature returns to within safe limits.
