The Texas Instruments BQ29400ADCT3 is a BiCMOS secondary protection IC for 2-, 3-, or 4-cell Lithium-Ion battery packs. It incorporates a high-accuracy, precision over-voltage detection circuit with a programmable delay time.
This device provides secondary protection, comparing each cell to an internal reference voltage. If a cell reaches an overvoltage condition, the protection sequence begins. The BQ29400ADCT3 features a low power consumption of less than 2 µA and a high accuracy over-voltage sense threshold of 4.40V ± 25mV.
It is suitable for applications such as notebook PCs, portable instrumentation, and medical and test equipment. The IC is available in a compact 8-LSSOP, 8-MSOP (0.110", 2.80mm Width) package and is designed for surface mounting.
Key specifications include a 2-4 cell count capability, Lithium Ion battery chemistry compatibility, and an operating temperature range of -25°C to 85°C.
