Description
This reference design is a complete solution that includes one bq27425-G2B 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 bq27425-G2B integrated circuit and all other onboard components necessary to monitor and predict capacity for a system-side fuel gauge solution. The reference design connects directly across the battery pack. With the EV2300 or EV2400 interface board and software, the user can:
Features
- # Series Cells: 1S
- Max Input Volts: 4.5V
- Max Charge Current: 2A
- Communication: I2C
- Integrated sense resistor
- This EVM requires the use of a communications tranciever, the EV2400.
