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-inte-grated charger. The bq2002C integrates fast charge with pulsed-trickle control in a single IC for charging one ormoreNiCdorNiMHbatterycells.
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 thefollowing:
Peakvoltagedetection(PVD)
Negativedeltavoltage(-V)
Maximumvoltage
Maximumtemperature
Maximumtime
After fast charge, the bq2002C pulsetrickles the battery per the preconfigured limits. Fast charge may be inhibited using the INH pin. The bq2002C may also be placed in low-standby-power mode to reduces systempowerconsumption.

Any time the voltage on the BAT pin exceeds the maximumcellvoltage,VMCV,fastchargeisterminated.
Maximum temperature termination occurs anytime the voltage on the TS pin falls below the temperature cut-off thresholdVTCO, where
VTCO =0.5*VCC ±5%.
Maximum charge time is configured using the TM pin.Time settings are available for corresponding charge rates of C/2, 1C, and 2C. Maximum time-out termination is enforced on the fast-charge phase, then reset, and enforced again on the top-off phase, if selected. There is notimelimitonthetrickle-chargephase.
