Working Principles

The NCP380HMUAJAATBG operates by comparing the input voltage (VIN) with a preset threshold voltage. If the input voltage exceeds the threshold, the active-low reset output (RESET) is triggered, indicating an overvoltage condition. Similarly, if the input voltage falls below the threshold, the reset output is activated, indicating an undervoltage condition.

The power-on reset delay ensures that the reset output remains inactive for a specific period after power is applied, allowing the system to stabilize before monitoring begins.
