The BQ2969TEVM evaluation module (EVM) is a complete evaluation system for the BQ2969T, a high accuracy, low-power overvoltage and overtemperature protector with an integrated LDO for 2-series to 4-series Li-Ion, and LiFePO4 battery packs. The EVM consists of a BQ2969T circuit module which is used for simple evaluation of the BQ2969T protection functions. The circuit module includes one BQ2969T integrated circuit (IC) and all other onboard components necessary to signal the conditions of overcharge, overdischarge, and overtemperature in a 4-series cell Li-Ion or Li-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.
