The BQ29414PWR from Texas Instruments is a secondary overvoltage protection IC specifically designed for 2-, 3-, or 4-cell lithium-ion battery packs. It incorporates a high-accuracy precision overvoltage detection circuit with a programmable delay for overvoltage detection time.
This device 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 bq2941x device starts charging an external capacitor through the CD pin. When the CD pin voltage reaches 1.2 V, the OUT pin changes from a low level to a high level.
Key features include low power consumption with ICC < 2 µA and a fixed high-accuracy overvoltage protection threshold. The operating temperature range is -40°C to 110°C. The BQ29414PWR is supplied in an 8-TSSOP package suitable for surface mounting.
Applications for the BQ29414PWR include 2nd-level overvoltage protection in Li-Ion battery packs for notebook computers, portable instrumentation, and other portable equipment.
