The BQ294702DSGR from Texas Instruments is a dedicated overvoltage monitor and protector for Lithium-Ion battery pack systems, supporting 2 to 4 series cells. Each cell is independently monitored for overvoltage conditions. The device features an external capacitor-programmed delay timer, which initiates upon detection of an overvoltage event. Upon expiration of this timer, the output is triggered to an active state, providing protection.
Key electrical specifications include a maximum input voltage of 20V and a typical operating current of 1µA. The overvoltage protection threshold can be factory programmed within a range of 3.85V to 4.6V, with specific thresholds including 4.125V, 4.22V, 4.25V, 4.3V, 4.4V, 4.5V, and 4.6V. The operating temperature range is -40°C to 110°C.
This IC is housed in an 8-pin WSON (2x2mm) package, suitable for surface mounting. The small package footprint and low power consumption make it ideal for compact battery management solutions. The BQ294702DSGR offers high-accuracy overvoltage protection with ±10mV precision and low leakage current per cell input (<100nA).
