説明
- TIDA-00031, This reference design is a complete evaluation system solution for the bq27421. The solution includes one bq27421 circuit module with an integrated current-sense resistor. A separated orderable EV2300 or EV2400 PC interface board for gas gauge interface along with a PC USB cable, and Windows-based PC software is needed when using this design. The circuit module includes one bq27421 integrated circuit and all other on-board components necessary to monitor and predict capacity for a system-side fuel gauge solution. The circuit module connects directly across the battery pack. With the EV2300 or EV2400 interface board and software, the user can: (1)Read the bq27421 data registers. (2)Program the chipset for different configurations. (3)Log cycling data for further evaluation
