Working Principles

The MAX16083AXR32B+T operates by monitoring the supply voltage and the activity of the microprocessor. When the supply voltage rises above the set threshold voltage, it generates a power-on reset signal to initialize the microprocessor. The watchdog timer continuously monitors the microprocessor's activity by checking the state of the WDI pin. If the microprocessor fails to toggle this pin within the specified timeout period, the MAX16083AXR32B+T generates a reset signal to restart the microprocessor.
