Working Principles

The MAX6313UK42D3-T operates by continuously monitoring the supply voltage connected to the VCC pin. When the voltage falls below the set threshold, the IC generates a reset signal on the RESET pin. The threshold voltage can be adjusted using external resistors to meet specific requirements.

The reset output is debounced to eliminate false triggering caused by voltage fluctuations or noise. The timeout period can be adjusted to control the duration of the reset signal. Once the supply voltage rises above the threshold, the reset signal is released.
