LM3622 Lithium-Ion Battery Charger Controller

Check for Samples: LM3622

FEATURES

DESCRIPTION

The LM3622 is a charge controller for Lithium-Ion

batteries. This monolithic integrated circuit accurately

controls an external pass transistor for precision

Lithium-Ion battery charging. The LM3622 provides a

constant voltage or constant current (CVCC)

configuration that changes, as necessary, to optimally

charge lithium-ion battery cells. Voltage charging

versions (4.1V, 4.2V, 8.2V, and 8.4V) are available

for one or two cell battery packs and for coke or

graphite anode battery chemistry.

•

Versions for Charging of 1 Cell (4.1V or 4.2V)

or 2 Cells (8.2V or 8.4V)

•

Versions for Coke or Graphite Anode

Precision (±30mV/Cell) End-of-Charge Control

Wide Input Range: 4.5V-24V

Low Battery Drain Leakage: 200nA

15 mA Available to Drive Low Cost PNP

APPLICATIONS

The LM3622 accepts input voltages from 4.5V to

24V. Controller accuracy over temperature is

±30mV/cell for A grade and ±50mV/cell for the

standard grade. No precision external resistors are

required. Furthermore, the LM3622's proprietary

output voltage sensing circuit drains less than 200nA

from the battery when the input source is

disconnected.

•

Cellular Phone Cradle Charger

PDA/Notebook Cradle Charger

Camcorder Cradle Charger

The LM3622 circuitry includes functions for regulating

the charge voltage with a temperature compensated

bandgap reference and regulating the current with an

external sense resistor. The internal bandgap insures

excellent controller performance over the operating

temperature and input supply range.

The LM3622 can sink 15mA minimum at the EXT pin

to drive the base of an external PNP pass transistor.

It also has low-voltage battery threshold circuitry that

removes this drive when the cell voltage drops below

a preset limit. The LV_SELpin programs this threshold

voltage to either 2.7V/cell or 2.15V/cell. The low-

voltage detection, which is a user enabled feature,

provides an output signal that can be used to enable

"wake up charge" source automatically to

precondition a deeply discharged pack.

The LM3622 is available in a standard 8-lead SOIC

surface mount package.
