Working Principles

BQ294706DSGR operates based on a combination of voltage and current sensing techniques. It continuously monitors the battery voltage and compares it to the predefined thresholds for overvoltage and undervoltage protection. In case of an overvoltage condition, the IC disconnects the battery from the load to prevent any potential damage. Similarly, during an undervoltage situation, it cuts off the battery to avoid deep discharge. The overcurrent protection feature detects excessive current flow and interrupts the circuit to protect the battery and connected components.
