POR (Power-on-Reset) generates a reset signal when power is first applied, ensuring the system starts from a known state. BOD (Brown-Out Detector) continuously monitors the supply voltage during operation and triggers a reset or interrupt if the voltage drops below a safe threshold, preventing erratic behavior.
The typical supply voltage range is 1.0–5.5 V, but the exact range depends on the specific model. Always check the datasheet for the exact operating range.
The threshold voltage is often set internally or via external resistors. It can be adjusted within a range (e.g., 0.8–4.5 V) depending on the device. The threshold accuracy is typically ±1.5%.
The reset timeout period is the duration of the reset pulse after voltage recovery. It ensures the system has stable power before starting. Typical values range from 1 to 200 ms, and the required value depends on the system's startup time.
