Texas Instruments BQ294582 Overvoltage Protection for 2-Series and 3-Series Cell Li-Ion Batteries, with 4.225v OVP BQ294582DRVT

The BQ294582DRVT is an overvoltage protection device designed for 2-series and 3-series cell Li-Ion battery packs. It features a fixed overvoltage protection (OVP) threshold of 4.225 V, ensuring high-accuracy monitoring with a tolerance of ±10 mV. The device includes a programmable delay timer with options for 4 seconds or 6.5 seconds, allowing for customizable response times to overvoltage conditions. It operates with low power consumption, drawing approximately 1 µA when the cell voltage is below the protection threshold, and has a low leakage current of less than 100 nA per cell input. The BQ294582DRVT is housed in a compact 6-pin SON package, making it suitable for applications in portable devices such as tablets, slates, power tools, and notebook computers.
