BQ2002D
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 The bq2002D/T Fast-Charge IC are low-cost CMOS battery-charge controllers able to provide reliable charge termination for both Ni Cd and Ni MH battery 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 control in a single IC for charging one or more Ni Cd or Ni MH battery cells. Fast charge is initiated on application of the charging supply or...
