Switch-mode Nicd/nimh Battery Charger With Negative Dv And Dt/dt Termination

  The BQ2003 Fast Charge IC provides comprehensive fast charge control functions together with high-speed switching power control circuitry on a monolithic CMOS device. Integration of closed-loop current control circuitry allows the BQ2003 to be the basis of a cost-effective solution for stand-alone and systemintegrated chargers for batteries of one or more cells. Switch-activated discharge-beforecharge allows bq2003-based chargers to support Battery conditioning and capacity determination. High-efficiency power conversion is accomplished using the BQ2003 as a hysteretic PWM Controller for switch-mode regulation of the charging current. The BQ2003 may alternatively be used to Gate an externally regulated charging current.
