The BQ29412DCTR is a secondary Overvoltage Protection IC for 2-, 3-, or 4-cell Li-ion battery packs that incorporates a high-accuracy precision overvoltage detection circuit. It includes a programmable delay circuit for overvoltage detection time. Each cell in a multiple-cell pack is compared to an internal reference voltage. If one cell reaches an overvoltage condition, the protection sequence begins. The BQ2941x device starts charging an external capacitor through the CD pin. When the CD pin voltage reaches 1.2V, the OUT pin changes from a low level to a high level.
● Fixed high accuracy overvoltage protection threshold
● Programmable delay time of detection
● High power supply ripple rejection
● Stable during pulse charge operation
● Green product and no Sb/Br
