Description and Introduction

Secondary Over-Voltage Protection for 2-4 cell in series Li-Ion/Poly (4.35V) 8-TSSOP -40 to 110 The **BQ29410PW** is a highly efficient, single-cell lithium-ion (Li-ion) battery protection IC designed to safeguard battery packs from overvoltage conditions. Developed for portable electronics, power tools, and other battery-powered applications, this component ensures reliable operation by monitoring cell voltage and initiating protective measures when thresholds are exceeded.  

Featuring a precision voltage detection circuit, the BQ29410PW responds quickly to overvoltage events, disconnecting the battery from the load to prevent damage. Its low power consumption makes it suitable for energy-sensitive applications, while its compact package (TSSOP-8) allows for easy integration into space-constrained designs.  

Key functionalities include adjustable overvoltage thresholds, a built-in delay timer to minimize false triggers, and a latch-mode operation that maintains protection until manually reset. These features enhance system safety and prolong battery life.  

Engineers favor the BQ29410PW for its robust performance, accuracy, and ease of implementation in battery management systems. Whether used in consumer electronics or industrial devices, this IC provides a critical layer of protection, ensuring both safety and efficiency in modern battery-powered solutions.
