The BQ29419PWR from Texas Instruments is a secondary overvoltage protection integrated circuit specifically designed for 2-, 3-, or 4-cell lithium-ion battery packs. It features a high-accuracy precision overvoltage detection circuit with a typical overvoltage protection threshold of 4.3V. The device operates within a temperature range of -40°C to 110°C and consumes very low operating current, typically 2 µA.
This IC includes a programmable delay circuit for overvoltage detection time, enhancing its flexibility in various applications. The BQ29419PWR is housed in an 8-TSSOP package, suitable for surface mount applications. Its primary function is to provide reliable battery protection, preventing damage to the battery pack from overvoltage conditions.
Applications for the BQ29419PWR include second-level overvoltage protection in Li-Ion battery packs for portable equipment such as notebook computers and portable instrumentation. The device compares each cell voltage to an internal reference, initiating a protection sequence when an overvoltage condition is detected.
