Working Principles

BQ294524DRVT operates by continuously monitoring the battery voltage through its input pins. When the voltage exceeds the set threshold, it triggers the overvoltage protection mechanism, disconnecting the load from the battery. Similarly, when the voltage drops below the specified threshold, the undervoltage protection feature cuts off the load. This ensures that the battery remains within safe operating limits.
