BQ2003SG4 Datasheet PDF - TI

●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
