Detailed Pin Configuration

ADM812RART-REEL7 has three pins:

1. VCC: This pin is connected to the positive supply voltage.
2. GND: This pin is connected to the ground or negative supply voltage.
3. RESET: This pin outputs a reset signal when the monitored voltage falls below the threshold.

Functional Features

• Monitors the supply voltage continuously.
• Generates a reset signal when the voltage drops below the set threshold.
• Provides a stable reset signal during power-up and power-down sequences.
• Offers an adjustable reset threshold voltage to suit different applications.

Advantages

• Reliable voltage monitoring and reset functionality.
• Low power consumption, making it suitable for battery-powered devices.
• Wide operating voltage range allows compatibility with various systems.
• Small package size enables usage in space-constrained designs.
• High accuracy ensures precise voltage monitoring.

Disadvantages

• Limited reset timeout period may not be suitable for all applications requiring longer timeouts.
• Fixed pin configuration limits flexibility in circuit design.

Working Principles

ADM812RART-REEL7 operates by comparing the supply voltage with the set threshold voltage. When the supply voltage falls below the threshold, the internal circuitry triggers the RESET pin, generating a reset signal. This signal remains active until the supply voltage rises above the threshold and stabilizes.
