bq2002C
NiCd/NiMH Fast-Charge Management IC
Features General Description вћ¤ The bq2002C Fast-Charge IC is a lowcost CMOS battery-charge controller
providing reliable charge termination
for both NiCd and NiMH battery applications. Controlling a current-limited
or constant-current supply allows the
bq2002C to be the basis for a costeffective stand-alone or system-integrated charger. The bq2002C integrates fast charge with pulsed-trickle
control in a single IC for charging one
or more NiCd or NiMH battery cells. вћ¤
вћ¤ Fast charge of nickel cadmium
or nickel-metal hydride batteries
Direct LED output displays
charge status
Fast-charge termination by -∆V,
maximum voltage, maximum
temperature, and maximum
time вћ¤ Internal band-gap voltage reference вћ¤ Selectable pulse-trickle charge
rates вћ¤ Low-power mode вћ¤ 8-pin 300-mil DIP or 150-mil
SOIC Pin Connections 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 …
