Product Information

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
  • Configurable, direct LED outputs display battery and charge status
  • Fast-charge termination by V, maximum voltage, maximum temperature, and maximum time
  • Optional top-off charge and pulsed current maintenance charging
  • Logic-level controlled low-power mode (< 5uA standby current)

Description

The bq2004E and bq2004H Fast Charge ICs provide 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 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 chargers to support battery conditioning and capacity determination.

High-efficiency power conversion is accomplished using the bq2004E/H as a hysteretic PWM controller for switch-mode regulation of the charging current. The bq2004E/H may alternatively be used to gate an externally regulated charging current.
