Functional Features

• Voltage monitoring: The MAX6425UK45+T continuously monitors the supply voltage and provides a reset signal when it falls below the programmed threshold.
• Manual reset: The manual reset input allows for an external reset signal to override the internal voltage monitoring.
• Push-pull reset output: The active-low push-pull reset output provides a reliable and immediate reset signal to the system.
• Adjustable threshold voltage: The threshold voltage can be adjusted using an external resistor, allowing for flexibility in different applications.

Advantages and Disadvantages

Advantages

• Wide supply voltage range allows for compatibility with various systems.
• Low quiescent current minimizes power consumption.
• Small package size enables usage in space-constrained designs.
• Adjustable threshold voltage provides customization options.

Disadvantages

• Limited reset threshold voltage range may not suit all applications.
• Lack of additional features such as hysteresis or watchdog timer.

Working Principles

The MAX6425UK45+T operates by continuously monitoring the supply voltage using an internal voltage reference. When the voltage falls below the programmed threshold, the reset output is activated, signaling a system reset. The manual reset input allows for an external reset signal to override the internal monitoring. The push-pull reset output ensures a reliable and immediate reset signal to the system.
