  • Fast charge termination by delta temperature/delta time (DT/Dt), negative delta voltage (-DV) or peak voltage detect, maximum temperature, maximum time, and maximum voltage
  • -DV/peak voltage detect, hold-off, top-off, maximum time, and number of cells are jumper-configurable
  • -DV/peak voltage detect, hold-off, top-off, maximum time, and number of cells are jumper-configurable
  • Programmable charge status display
  • Discharge-before-charge control with push-button switch or auto discharge-before-charge with jumper
  • Inhibit fast charge by logic-level input

Texas Instruments  DV2004ES1

The DV2004ES1 Development System provides a development environment for the bq2004, bq2004E, or bq2004H Fast-Charge IC. The DV2004ES1 incorporate a bq2004/E/H and a buck-type switch-mode regulator to provide fast charge controls for 4 to 10 NiCd or NiMH cells.

The fast charge is terminated by any of the following: DT/Dt, -DV or peak voltage detect, maximum temperature, maximum time, maximum voltage, or an inhibit command. Jumper settings select the voltage termination mode, the hold-off, top-off, and maximum time limits, and automatic discharge-before-charge.

The user provides a power supply and batteries. The user configures the DV2004ES1 for the number of cells, voltage, charge termination mode, and maximum charge time (with or without top-off), and commands the discharge-before-charge option with the push-button switch S1.

Please review the bq2004/E/H data sheet, before using the DV2004ES1 board.
