Product Description

Texas Instruments BQ24040DSQR is a single-cell Li-ion battery charger IC offering integrated power management for portable devices. It supports input sources like USB or AC adapters with a voltage range of 4.35V to 6.5V and delivers up to 1A charging current. Designed for compact applications, it features built-in thermal regulation, charge termination, and safety protections (overvoltage, reverse leakage). Operating at -40°C to 85°C, it suits consumer electronics, medical devices, and IoT systems. Key advantages include high integration (no external FETs required), adaptive charging, and low standby current. Limitations include lack of direct communication interfaces. Optimized for single-cell Li-ion batteries, it simplifies design while ensuring efficient, reliable charging.
