Working Principles

The MAX6315US26D3+TG24 operates by continuously monitoring the supply voltage using an internal voltage reference. When the supply voltage drops below the threshold voltage, the IC asserts a reset signal to ensure proper system initialization. Additionally, the watchdog timer feature monitors a specific input signal and generates a reset if it fails to toggle within the specified timeout period. This helps prevent system lock-ups or malfunctions.
