The BQ29410DCTR from Texas Instruments is a secondary over-voltage protection integrated circuit specifically designed for 2, 3, or 4-cell Lithium-Ion battery packs. It incorporates a high-accuracy, precision overvoltage detection circuit and a programmable delay for detection time.
Key electrical specifications include a typical operating current of 2µA and a maximum input voltage of 25V. The overvoltage protection threshold is set at 4.35V, with minimum and maximum battery overvoltage protection limits of 4.325V and 4.375V, respectively. The device operates across a wide temperature range of -40°C to 110°C.
This IC is suitable for applications requiring 2nd-level overvoltage protection in Li-Ion battery packs, such as notebook computers, portable instrumentation, and other portable equipment. It is available in Surface Mount packaging, specifically the 8-LSSOP and 8-MSOP (0.110", 2.80mm Width) packages.
The BQ29410DCTR functions by comparing each cell in a multiple-cell pack to an internal reference voltage. If a cell reaches an overvoltage condition, a protection sequence is initiated, starting the charging of an external capacitor via the CD pin. When the CD pin voltage reaches 1.2V, the OUT pin transitions from low to high, indicating protection activation.
