BQ2004H - Fast Chargeer

Download the BQ2004H datasheet PDF. This datasheet also covers the BQ2004E variant, as both devices belong to the same fast chargeer family and are provided as variant models within a single manufacturer datasheet.

General 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.

Key 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 ∆ temperature/∆ time, peak volume detection, -∆V, maximum vol.
