• Reset Timeout Period: Fixed at 140ms
• Operating Temperature Range: -40°C to +85°C

Detailed Pin Configuration

The MAX801MEPA+ has the following pin configuration:

1. GND (Ground)
2. MR (Manual Reset)
3. VCC (Supply Voltage)
4. RESET (Reset Output)
5. TH (Threshold Adjust)
6. CT (Capacitor)
7. CT (Capacitor)
8. NC (No Connection)

Functional Features

• Voltage monitoring: The MAX801MEPA+ continuously monitors the supply voltage and compares it to the user-adjustable threshold voltage.
• Reset signal generation: When the supply voltage falls below the threshold voltage, the MAX801MEPA+ generates a reset signal to initiate a system reset.
• Manual reset input: The MR pin allows for manual reset control, overriding the automatic reset function.
• Adjustable threshold voltage: The TH pin enables the user to set the desired threshold voltage for voltage monitoring.

Advantages and Disadvantages

Advantages

• Low power consumption: The MAX801MEPA+ operates with minimal power requirements, making it suitable for battery-powered devices.
• Wide operating voltage range: It can work with supply voltages ranging from 1.0V to 5.5V, providing flexibility in various applications.
• Small package size: The compact 8-pin PDIP package allows for space-efficient integration into electronic circuits.

Disadvantages

• Fixed reset timeout period: The reset timeout period of 140ms may not be adjustable, limiting its suitability for certain applications requiring different timeout durations.
• Limited pin configuration options: The MAX801MEPA+ has a fixed pin configuration, which may restrict its compatibility with specific circuit designs.

Working Principles

The MAX801MEPA+ operates based on a voltage comparator circuit. It continuously compares the supply voltage with the user-adjustable threshold voltage. When the supply voltage falls below the threshold voltage, the IC generates a reset signal, initiating a system reset. The manual reset input allows for additional control over the reset function.

Detailed Application Field Plans

The MAX801MEPA+ finds application in various electronic devices that require voltage monitoring and reset functionality. Some potential application fields include:

1. Microcontrollers: Ensuring proper operation by monitoring the supply voltage and initiating a reset when necessary.
2. Power management systems: Protecting sensitive components by monitoring voltage levels and triggering appropriate actions.
3. Battery-powered devices: Optimizing battery life by monitoring voltage and managing power consumption efficiently.
4. Industrial automation: Providing reliable reset functionality in control systems to maintain operational stability.

Detailed and Complete Alternative Models

1. MAX803MEUK+: Similar to MAX801MEPA+, but available in a smaller SOT23-5 package.
2. MAX809MEUR+: Offers adjustable reset timeout period in addition to voltage monitoring capabilities.
3. MAX811MEUS+: Provides a push-pull reset output instead of an open-drain output.

These alternative models offer similar functionality to the MAX801MEPA+ and can be considered based on specific application requirements.
