Product Description

The BQ29700DSET from Texas Instruments is a highly efficient single-cell lithium protection IC designed for safeguarding Li-ion and Li-polymer batteries. It integrates critical protection features against overvoltage, undervoltage, overcurrent, and short-circuit conditions. The IC operates with a single-cell input (1-series) and provides two output control signals for external MOSFETs, enabling direct connection to battery modules. It supports a voltage range of 2.5V to 5.5V and operates across an industrial temperature range of -40°C to +85°C. Ideal for portable electronics, medical devices, and energy storage systems, the BQ29700DSET excels in precision voltage monitoring and ultra-low quiescent current. However, it lacks built-in communication interfaces, limiting advanced system diagnostics. Its compact design ensures minimal PCB footprint, though external component selection is critical for optimal performance in high-current applications.
