Part Number : DV2954S1
Function : Control of On-Board PNP Switch-Mode Regulator with Low-Side Current Sensing
Manufacturers : Texas Instruments
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 – IMAXdivided 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.
