Specifications

• Supply Voltage Range: 1.2V to 5.5V
• Threshold Voltage Options: 4.4V
• Reset Timeout Period: Adjustable from 1ms to 1600ms
• Operating Temperature Range: -40°C to +85°C

Detailed Pin Configuration

The MAX6313UK44D1-T has four pins:

1. VCC: Power supply input pin
2. GND: Ground pin
3. RESET: Active-low reset output pin
4. MR: Reset timeout period adjustment pin

Functional Features

• Monitors the voltage level of the power supply continuously.
• Generates a reset signal when the voltage falls below the threshold.
• The reset signal remains active until the voltage rises above the threshold for a specified timeout period.
• The reset timeout period can be adjusted using an external capacitor connected to the MR pin.

Advantages and Disadvantages

Advantages: - Low-power consumption - Precision voltage monitoring - Adjustable reset timeout period - Small package size

Disadvantages: - Limited threshold voltage options - Single-channel monitoring

Working Principles

The MAX6313UK44D1-T operates by comparing the supply voltage with a fixed threshold voltage. When the supply voltage drops below the threshold, the reset output is activated. The reset output remains active until the supply voltage rises above the threshold for a specified timeout period. The reset timeout period can be adjusted using an external capacitor connected to the MR pin.

Detailed Application Field Plans

The MAX6313UK44D1-T is commonly used in various applications where reliable power supply monitoring and reset functionality are required. Some of the typical application fields include:

1. Microcontrollers and Microprocessors: Ensuring proper system initialization and preventing erratic behavior during power-up or brownout conditions.
2. Communication Systems: Providing a reset signal to restart the system in case of power disturbances or faults.
3. Industrial Control Systems: Monitoring power supply integrity and initiating system reset when necessary.
4. Automotive Electronics: Preventing malfunctions by resetting electronic control units during voltage fluctuations or power loss events.

Detailed and Complete Alternative Models

1. MAX6314UK46D3-T: Similar to MAX6313UK44D1-T but with a different threshold voltage option (4.6V).
2. MAX6315UK47D2-T: Similar to MAX6313UK44D1-T but with a different threshold voltage option (4.7V) and fixed reset timeout period (1600ms).
3. MAX6316UK48D1-T: Similar to MAX6313UK44D1-T but with a different threshold voltage option (4.8V) and adjustable reset timeout period.

These alternative models provide flexibility in choosing the appropriate voltage monitoring and reset circuit based on specific application requirements.
