The BQ771612DPJR from Texas Instruments is an integrated circuit designed for robust overvoltage protection in Lithium-Ion battery pack systems. It supports battery configurations from 2 to 4 series cells, monitoring each cell independently to detect overvoltage conditions.
Key electrical features include high-accuracy overvoltage protection with a tolerance of ±10 mV, ensuring precise safeguarding. The device operates with very low power consumption, drawing approximately 1 µA when cell voltages are below the protection threshold, and exhibits low leakage current per cell input, less than 100 nA. An external capacitor-programmed delay timer is incorporated, initiating upon detection of an overvoltage condition and triggering the output driver upon expiration.
This IC is housed in a compact 8-pin WSON package with dimensions of 3.00 mm x 4.00 mm, suitable for space-constrained applications. The mounting type is surface mount, facilitating integration into PCB designs. The operating temperature range is -40°C to 85°C, making it suitable for a variety of environmental conditions.
