Part Number : BQ2004EPN
Function : Fast-Charge ICs
Maker : Texas Instruments
The bq2004E and bq2004H FastCharge ICs provide comprehensive
fast charge control functions together with high-speed switching power con
trol circuitry on a monolithic CMOS device.
Integration of closed-loop current control circuitry allows the bq2004
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 bq2004E/H-based charg
ers to support battery conditioning and capacity determination.
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
Configurable, direct LED outputs display battery and charge status
Fast-charge termination by∆tem perature/∆time, peak volume detection, -∆V, maximum voltage,maximum temperature, and maximum time
Optional top-off charge and pulsed current maintenance charging
Logic-level controlled low-power mode (< 5µA standby current)
