The Texas Instruments BQ29419PW 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 and includes a programmable delay for detection time.
Key electrical specifications include a maximum input voltage of 25V and an overvoltage protection threshold of 4.3V. The typical operating current is a low 2 µA, making it suitable for power-sensitive applications. The device offers battery overvoltage protection with a minimum threshold of 4.275V and a maximum of 4.325V.
This IC is housed in an 8-TSSOP package, suitable for surface mount applications. Its operating temperature range is from -40°C to 110°C.
Applications for the BQ29419PW include 2nd-level overvoltage protection in Li-Ion battery packs for portable instrumentation, notebook computers, and other portable equipment.
