Detailed Pin Configuration

ADM812SARTZ-REEL has three pins:

1. VCC: Power supply input pin.
2. GND: Ground reference pin.
3. RESET: Output pin that generates a reset signal when the monitored voltage falls below the threshold.

Functional Features

• Monitors the voltage level of the system continuously.
• Generates a reset signal when the voltage falls below the set threshold.
• Provides a stable reset output during power-up and power-down sequences.
• Offers a wide range of reset threshold voltage and timeout period options for flexibility.

Advantages

• Low power consumption makes it suitable for battery-powered devices.
• Small package size allows for space-efficient designs.
• Wide operating voltage range enables compatibility with various systems.
• High accuracy ensures reliable voltage monitoring.

Disadvantages

• Limited reset threshold voltage and timeout period options may not meet the requirements of all applications.
• Lack of additional features, such as hysteresis adjustment, may limit its use in certain scenarios.

Working Principles

ADM812SARTZ-REEL operates by comparing the monitored voltage with the set threshold voltage. When the voltage falls below the threshold, the internal circuitry triggers the RESET pin, generating a reset signal. This signal remains active until the voltage rises above the threshold or the specified timeout period elapses.

Detailed Application Field Plans

ADM812SARTZ-REEL finds applications in various electronic devices where voltage monitoring and reset functions are critical. Some common application fields include:

1. Microcontrollers: Ensuring proper system initialization and recovery after power disruptions.
2. Industrial Control Systems: Preventing malfunctions due to voltage fluctuations.
3. Automotive Electronics: Monitoring battery voltage and initiating system resets if necessary.
4. Medical Devices: Ensuring reliable operation by monitoring power supply integrity.
5. Consumer Electronics: Protecting sensitive components from voltage-related issues.
