The BQ29412DCTT from Texas Instruments is a secondary overvoltage protection integrated circuit specifically designed for 2, 3, or 4-cell Lithium-Ion battery packs. This device incorporates a high-accuracy precision overvoltage detection circuit and a programmable delay for overvoltage detection time.
Key electrical specifications include a typical operating current of 2 µA and a maximum input voltage of 25V. The overvoltage protection threshold is set at 4.45V, with minimum and maximum thresholds at 4.425V and 4.475V respectively. The operating temperature range spans from -40°C to 110°C.
The BQ29412DCTT is suitable for applications requiring 2nd-level overvoltage protection in Li-Ion battery packs, such as notebook computers, portable instrumentation, and portable equipment. It is available in an 8-LSSOP, 8-MSOP package and is designed for surface mount installation.
This IC compares each cell in a multiple-cell pack to an internal reference voltage. If one cell reaches an overvoltage condition, the protection sequence begins. The device starts charging an external capacitor through the CD pin, and when the CD pin voltage reaches 1.2V, the OUT pin changes from a low level to a high level, indicating protection activation.
