The BQ76922 evaluation module (EVM) is a complete evaluation system for the BQ76922, a three-cell to five-cell lithium-ion (Li-ion) battery monitor integrated circuit. The EVM consists of a BQ76922 circuit module which is used for simple evaluation of the BQ76922 monitor function. The circuit module includes one BQ76922 integrated circuit (IC), sense resistor, power FETs and all other onboard components necessary to protect the cells from overcharge, over discharge, short circuit and overcurrent discharge in a five-series cell Li-ion or lithium-polymer battery pack. The circuit module connects directly across the cells in a battery or can be connected with a power supply and the included cell simulator resistors. With the onboard interface or compatible external interface board and Microsoft® Windows® based PC graphical user interface (GUI) software, the user can view the device registers, adjust protection limits and enable FET control outputs.
