Texas Instruments  DV2002L2

The DV2002L2 Development System provides a development environment for the bq2002 Fast-Charge ICs. The DV2002L2 incorporates a bq2002 and a linear regulator to provide fast charge control for 4 to 10 NiMH cells.

The fast charge is terminated by any of the following: -delta V/peak voltage, maximum temperature, maximum time, and inhibit command for the bq2002. Jumper settings select the top-off and maximum time limits.

The user provides a power supply and batteries. The user configures the DV2002L2 for the number of cells and maximum charge time (with or without topoff).

Please review the bq2002 data sheet before using the DV2002L2 board.
