The DV2054S2 Development System provides a development environment for the bq2054 Lithium Ion Fast-Charge IC. The DV2054S2 incorporates a bq2054 and a buck-type switch-mode regulator to provide fast charge control for 1 through 4 Li-Ion cells.

Fast charge is preceded by a pre-charge qualification period.

Fast charge termination occurs on:

  • Minimum current - IMAX divided by 10, 20, or 30
  • Maximum time-out

The bq2054 can be reset and a new charge cycle started by applicaton of power to the board or battery replacement.

The user provides a DC power supply and batteries and configures the board for the number of cells, the minimum current threshold, and the LED display mode. The board has direct connections for the battery and the provided thermistor.

Before using the DV2054S2 board, please review the bq2054 data sheet.
