General Description

The bq2002C Fast-Charge IC is a low-

cost CMOS battery-charge controller

providing reliable charge termination

for both NiCd and NiMH battery appli-

cations.

Controlling a current-limited

or constant-current supply allows the

bq2002C to be the basis for a cost-

effective stand-alone or system-inte-

grated charger.

The bq2002C inte-

grates fast charge with pulsed-trickle

control in a single IC for charging one

or more NiCd or NiMH battery cells.

Fast charge is initiated on application

of the charging supply or battery

replacement. For safety, fast charge is

inhibited if the battery temperature

and voltage are outside configured

limits.

Fast charge is terminated by any of

the following:

n Peak voltage detection (PVD)

n Negative delta voltage (-

∆V)

n Maximum voltage

n Maximum temperature

n Maximum time

After fast charge, the bq2002C pulse-

trickles the battery per the pre-

configured limits. Fast charge may be

inhibited using the INH pin.

The

bq2002C may also be placed in low-

standby-power mode to reduce

system power consumption.
