DV2003L1 描述
The DV2003L1 Development System provides a development environment for the bq2003 Fast-Charge IC. The DV2003L1 incorporates a bq2003 and an LM317 linear regulator to provide fast charge control for 4 to 14 NiCd or NiMH cells. The DV2003L1 also supports on/off control of an external current source.
The fast charge is terminated by any of the following: DT/Dt,-DV, maximum temperature, maximum time, maximum voltage, or an external inhibit command.
Jumper settings select the -DV enabled state, the hold-off, top-off, and maximum time limits, and enable the use of an external current source.
The user provides a power supply and batteries. If the on-board 1.25A linear regulator is disabled, the external current source must have an appropriate digitally controlled switch (active high). The user configures the DV2003L1 for the number of cells, charge termination, maximum charge time (with or without top-off), and commands the discharge-before-charge option with the push-button switch S1
