LTC1731-4.1/LTC1731-4.2

Single Cell Lithium-Ion Linear

Battery Charger Controllers

FEATURES

DESCRIPTIO

Complete Linear Charger Controller for

1-Cell Lithium-Ion Batteries

1% Voltage Accuracy

Programmable Charge Current

C/10 Charge Current Detection Output

Programmable Charge Termination Timer

Space Saving 8-Pin MSOP Package

Automatic Sleep Mode When Input Supply

is Removed (7µA Battery Drain)

Automatic Trickle Charging of Low Voltage Cells

Programmable for Constant-Current-Only Mode

The LTC

1731 is a complete constant-current/constant-

voltage linear charger controller for single cell lithium-ion

batteries. Nickel-cadmium (NiCd) and nickel-metal-hy-

dride (NiMH) batteries can also be charged with constant

current using external termination. The external sense

resistor sets the charge current with 5% accuracy. An

internal resistor divider and precision reference set the

final float potential with

±1%

accuracy. The output float

voltage is set internally to 4.1V (LTC1731-4.1) or 4.2V

(LTC1731-4.2).

When the input supply is removed, the LTC1731 automati-

cally enters a low current sleep mode, dropping the battery

drain current to typically 7µA. An internal comparator

detects the end-of-charge (C/10) condition while a pro-

grammable timer, using an external capacitor, sets the

total charge time. Fully discharged cells are automatically

trickle charged at 10% of the programmed current until

cell voltage exceeds 2.457V.

The LTC1731 is available in the 8-pin MSOP and SO

packages.
