DV2954S1L 描述

The DV2954S1L Development System provides a development environment for the bq2954 Lithium Ion Fast-Charge IC. The DV2954S1L incorporates a bq2954 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, 15, or 20
• Maximum time-out

The bq2954 can be reset and a new charge cycle started by applicaton of power to the board or battery replacement. The board automatically initiates a recharge when the battery voltage drops to 3.85V per cell.

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 DV2954S1L board, please review the bq2954 data sheet.
