BQ2003 具有负 dV 和 dT/dt 终端的镍镉电池/镍氢电池开关模式充电管理 IC
BQ2003 描述
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.
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
