NiCd/NiMH Fast-Charge Management ICs
Features
General Description
Fast charge is terminated by any of
?
Fast charge of nickel cadmium
or nickel-metal hydride batter-
The bq2002E and bq2002G Fast-
Charge ICs are low-cost CMOS bat-
the following:

able charge termination for both NiCd
and NiMH battery applications. Con-

stant-current supply allows t h e
bq2002E/G to be the basis for a cost-
effective stand-alone or system-inte-
grated charger. The bq2002E/G inte-
grates fast charge with optional top-off
and 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 re-
placement. For safety, fast charge is
inhibited if the battery temperature
and voltage are outside configured
limits.
n Maximum temperature
n Maximum time
After fast charge, the bq2002E/G op-
tionally tops-off and pulse-trickles the
battery per the pre-configured limits.
Fast charge may be inhibited using
the INH pin. The bq2002E/G may
also be placed in low-standby-power
mode to reduce system power con-
sumption.
T h e bq2002E differs from t h e
bq2002G only in that a slightly dif-
ferent set of fast-charge and top-off
time limits is available. All differ-
ences between the two ICs are illus-
trated in Table 1.
