The BQ29410DCT3R from Texas Instruments is a high-accuracy secondary over-voltage protection IC specifically designed for 2-, 3-, or 4-cell Lithium-Ion battery packs. This device incorporates a precision overvoltage detection circuit and a programmable delay for detection time, ensuring reliable battery protection.
Key electrical specifications include a maximum input voltage (Vin max) of 25V and a typical operating current (Icc) of less than 2µA when all cells are below the protection threshold. The overvoltage protection threshold is set at 4.35V, with a minimum detection of 4.325V and a maximum of 4.375V. The operating temperature range spans from -40°C to 110°C.
This IC functions by comparing each cell voltage to an internal reference. Upon detecting an overvoltage condition in any cell, it initiates a protection sequence. The BQ29410DCT3R is suitable for applications requiring second-level overvoltage protection in Li-Ion battery packs, such as notebook computers, portable instrumentation, and other portable equipment.
The BQ29410DCT3R is available in an 8-pin SM8 package, specifically an 8-LSSOP or 8-MSOP with a 2.80mm width, and is designed for surface mount applications.
