Description
General part information
BQ2003 Series
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 system-integrated chargers for batteries of one or more cells.
Switch-activated discharge-before-charge allows bq2003-based chargers to support battery conditioning and capacity determination.
