Description
The bq2004 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 bq2004 to be the basis of a cost-effective solution for stand-alone and system integrated chargers for batteries of one or more cells. Switch-activated discharge-before charge allows bq2004-based chargers to support battery conditioning and capacity determination. High-efficiency power conversion is accomplished using the bq2004 as a hysteretic PWM controller for switch-mode regulation of the charging current. The bq2004 may alternatively be used to gate an externally regulated charging current. View All Description in Datasheet |
