Working Principles

The MAX16072RS17D2+T operates by continuously monitoring the supply voltage. When the voltage falls below the set threshold, the IC generates a reset signal to initiate a system reset. The reset timeout period can be adjusted according to the application requirements. Additionally, the watchdog timer function detects system malfunctions by monitoring an external input. If the watchdog input is not toggled within the specified time, a reset signal is generated. The manual reset input allows external control over the reset signal.
