bq34z100EVM Wide Range Impedance Track™ Enabled
Battery Fuel Gauge Solution
This evaluation module (EVM) is a complete evaluation system for the bq34z100 wide-range fuel gauge
for lithium ion, Nickel metal hydride (NiMH) and Nickel Cadmium (NiCd) chemistries when combined with
an EV2300 USB adapter and Microsoft
®
Windows
®
based PC software downloadable from the TI.com
website. The circuit module includes one bq34z100 integrated circuit (IC) and all other components
necessary to monitor and predict capacity in one or more series cell Li-ion, Li-polymer, or LiFePO4 battery
packs. The minimum series cell count for PbA, NiMH, and NiCd chemistries must exceed 3.3-V stack
voltage. The circuit module connects directly across the battery stack. With the EV2300 interface adapter
and software, it is possible to read the bq34z100 data registers, program the chip for different pack
configurations, log cycling data for further evaluation, and evaluate the overall functionality of the
bq34z100 solution under different charge and discharge conditions.
