Working Principles

The TPS259231DRCT operates based on a comparator circuit that continuously monitors the input voltage and output current. When the input voltage exceeds the set overvoltage threshold or the output current surpasses the set overcurrent threshold, the device quickly disconnects the load from the power supply to protect it from potential damage. The enable pin provides control over the device's operation, allowing it to be enabled or disabled as required.
