Description
The BQ2969EVM evaluation module (EVM) is a complete evaluation system for the BQ2969, a high accuracy, low-power overvoltage protector with an integrated LDO for 2-series to 4-series Li-Ion, and LiFePO4 battery packs. The EVM consists of a BQ2969 circuit module which is used for simple evaluation of the BQ2969 protection functions. The circuit module includes one BQ2969 integrated circuit (IC) and all other onboard components necessary to signal the conditions of overcharge and overdischarge 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.
Features
- Complete evaluation system for the BQ2969 2-cell to 4-cell Li-Ion high accuracy battery overvoltage protector
- Populated circuit module for 4-cell configuration for quick setupPower connections available on test points
- Resistor cell simulator for quick setup with only a power supply
Typical applications
- Notebook PCs, Ultrabooks
- UPS battery backup systems
- Portable medical electronics
