2. MR (Manual Reset Input)
3. RESET (Reset Output)
4. VCC (Supply Voltage)
5. TH (Threshold Adjust)

Functional Features

• Accurate voltage monitoring and control
• Adjustable reset threshold voltage
• Manual reset input for system control
• Power-on reset delay for stable system startup

Advantages and Disadvantages

Advantages

• Wide operating temperature range allows for use in various environments
• Small package size enables space-saving designs
• Low quiescent current minimizes power consumption
• Adjustable reset threshold voltage provides flexibility in voltage monitoring

Disadvantages

• Limited supply voltage range (1.2V to 5.5V)

Working Principles

The MAX6423XS27+T operates by continuously monitoring the supply voltage. It compares the voltage level with the adjustable threshold voltage set by the TH pin. If the supply voltage falls below the threshold, the RESET pin is asserted, indicating a low-voltage condition. The manual reset input (MR) can be used to override the monitoring function and manually reset the system.
