具有负 dV 和 dT/dt 终端的开关模式镍镉电池/镍氢电池充电器 16-PDIP 0 to 70
General Description
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 so lution for stand-alone and system integrated chargers for batteries of one or more cells.
Features
➤ Fast charge and conditioning of nickel cadmium or nickel-metal hydride batteries
➤ Hysteretic PWM switch-mode current regulation or gated control of an external regulator
➤ Easily integrated into systems or used as a stand-alone charger
➤ Pre-charge qualification of temperature and voltage
➤ Direct LED outputs display battery and charge status
➤ Fast-charge termination by ∆ temperature/∆ time, -∆V, maximum voltage, maximum temperature, and maximum time
➤ Optional top-off charge
