BQ2004H Datasheet Fast Chargeer

Manufacturer: Benchmarq

Overview: bq2004E/H Fast-Charge ICs.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The bq2004E and bq2004H Fast Charge ICs provide prehensive 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 systemintegrated chargers for batteries of one or more cells.

Switch-activated discharge-beforecharge allows bq2004E/H-based chargers to support battery conditioning and capacity determination.

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.
