General Description

The bq2002D/T Fast-Charge IC are

low-cost CMOS battery-charge control-

lers able to provide reliable charge ter-

mination for both NiCd and NiMH bat-

tery applications.

Controlling a

current-limited or constant-current

supply allows the bq2002D/T to be the

basis for a cost-effective stand-alone or

system-integrated charger.

The

bq2002D/T integrates fast charge with

optional top-off and pulsed-trickle con-

trol 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 re-

placement. 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 Rate of temperature rise

n Maximum voltage

n Maximum temperature

n Maximum time

After fast charge, the bq2002T option-

ally tops-off and pulse-trickles the

battery per the pre-configured limits.

Fast charge may be inhibited using

the INH pin. The bq2002D/T may be

placed in low-standby-power mode to

reduce system power consumption.
