Product Description

The BQ29700DSER lithium protector is a single-cell Li-ion protection IC designed for battery management systems, providing robust safeguarding against overvoltage, undervoltage, overcurrent, and short-circuit conditions. Operating within a voltage range of 2.5V to 5.5V, the BQ29700 battery management IC supports direct integration with external MOSFETs for charge/discharge control and features a compact design for space-constrained applications. It operates across an industrial temperature range of -40°C to +85°C, making it suitable for portable electronics, power tools, and energy storage systems. With precise voltage detection thresholds and adjustable delay timers, the BQ29700DSER Li-ion protection IC ensures high reliability and low quiescent current (1.5µA typical). While it lacks built-in communication interfaces, its simplicity and durability cater to cost-sensitive designs. Typical applications include consumer devices, medical equipment, and backup power solutions. Key advantages include fault tolerance and thermal protection, though external components are required for full functionality. The IC supports battery capacities up to 10Ah, ensuring compatibility with diverse Li-ion configurations.
