Texas Instruments DV2004L1

The DV2004L1 Development System provides a development environment for the bq2004 Fast-Charge IC. The DV2004L1 incorporates a bq2004 and a frequency-modulated linear regulator to provide fast charge control 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 DV2004L1 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 data sheet before using the DV2004L1 board.
