bq2004e/h fast charge ic integrates closed-loop current control circuitry, making it a cost-effective solution for stand-alone and system-integrated chargers for batteries of one or more cells.
The UNITRODE bq2004E/H Fast-Charge ICs provide comprehensive fast charge control functions together with high-speed switching power control circuitry on a monolithic CMOS device. These chips are designed to be the basis of cost-effective solutions for stand-alone and system-integrated chargers for batteries of one or more cells.
The bq2004E/H samples the voltage at the BAT pin once every 34 seconds.
