LTC4006

4A, High Efficiency,

Standalone Li-Ion

Battery Charger

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.

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-

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.
