bq28z560-R1 Single Cell Li-Ion Battery Gas Gauge and
Protection EVM
NOTE: Before starting: Download the latest revision of the device firmware and the evaluation
software from the TI bq28z560-R1 product page at http://www.ti.com. Go to the Tools and
Software section. For step-by-step instructions on reprogramming the device firmware, refer
to Section 9.3.
This evaluation module (EVM) is a complete evaluation system for the bq28z560-R1 battery management
solution. The EVM includes one bq28z560-R1 circuit module, a current sense resistor, and one thermistor.
An EV2300 or EV2400 PC interface board is required to interface to the gas gauge, and a PC USB cable
is required for communication with a PC. Both are ordered online at http://power.ti.com. Windows
®
-based
PC software is available online as well. The circuit module includes one bq28z560-R1 IC, and all other
onboard components necessary to monitor and predict capacity, monitor critical parameters, and protect
the cell from overcharge, over discharge, short circuit, and overcurrent in single-cell Li-Ion or Li-Polymer
battery packs. The EV2300 or EV2400 interface board and software the user can read the bq28z560-R1
data registers, program the chipset for different configurations, log cycling data for further evaluation, and
evaluate the overall functionality of the bq28z560-R1 under different charge and discharge conditions.
