The Texas Instruments BQ294704DSGR is a battery protection integrated circuit designed for 2-series to 4-series Li-Ion battery pack systems. It provides accurate, independent monitoring of each cell for overvoltage conditions.
Key features include an external capacitor-programmed delay timer, factory-programmed OVP thresholds ranging from 3.85V to 4.6V, and output options for active high or open-drain active low. The device boasts high-accuracy overvoltage protection with a tolerance of ±10 mV, low power consumption typically at 1 µA, and low leakage current per cell input.
This IC is housed in a compact 8-pin WSON package measuring 2.00 mm x 2.00 mm, making it suitable for space-constrained applications. The operating temperature range is -40°C to 85°C. The BQ294704DSGR is recommended for new designs and is available in a 3000-piece Tape & Reel package.
Applications include battery management systems for portable electronics, power tools, and electric vehicles where reliable overvoltage protection is critical.
