Reference Designs
System-side Impedance Track™ fuel (gas) gauge reference design
Texas Instruments
This reference design 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.
Features
