Working Principles

The MAX6387LT46D4+T operates by continuously monitoring the power supply voltage through the VCC pin. When the voltage falls below the set threshold, the circuit triggers a reset signal on the RESET pin. The threshold level can be adjusted using the TH pin to meet specific system requirements. The MR pin allows for manual reset control, enabling external reset initiation. The fixed reset timeout period ensures that the reset signal remains active for a specified duration to guarantee proper system reset.
