Working Principles
The MAX6386LT28D7+T operates by continuously monitoring the power supply voltage connected to its VCC pin. When the voltage falls below the user-defined reset threshold, the circuit triggers a reset signal on the RESET pin. This signal remains active until the voltage rises above the threshold or a manual reset is applied to the MR pin. The fixed reset timeout period ensures that the system recovers properly after power is restored.
