FEATURES
➤ Fast charge of nickel cadmium or nickel-metal hydride batteries ➤ Direct LED output displays charge status ➤ Fast-charge termination by rate of rise of temperature, maximum voltage, maximum temperature, and maximum time ➤ Internal band-gap voltage reference ➤ Optional top-off charge (bq2002T only) ➤ Selectable pulse-trickle charge rates (bq2002T only) ➤ Low-power mode ➤ 8-pin 300-mil DIP or 150-mil SOIC Pin Connections GENERAL DESCRIPTION
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. Fast charge is initiated on application of the charging supply or battery replacement. Pin Names 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 optionally tops-off and pulse-trickles the battery per the pre-configured limits. Fast charge may be inhibited using the INH pin.
