Detailed Pin Configuration

ADM823RYRJZ-R7 has three pins:

1. VCC: Connect this pin to the positive supply voltage.
2. GND: Connect this pin to the ground.
3. RESET: This pin outputs a low signal when the monitored voltage drops below the set threshold.

Functional Features

• Voltage monitoring: ADM823RYRJZ-R7 continuously monitors the input voltage and provides a reset signal when it falls below the set threshold.
• Adjustable threshold: The reset threshold voltage can be adjusted within a specified range to suit different system requirements.
• Reset timeout: If the voltage remains below the threshold for a specific period, the reset signal is deactivated to prevent continuous resetting.
• Low power consumption: The IC operates with minimal power consumption, making it suitable for battery-powered applications.

Advantages and Disadvantages

Advantages

• Wide operating voltage range allows compatibility with various systems.
• Adjustable threshold voltage provides flexibility in different applications.
• Small package size enables space-saving designs.
• High accuracy ensures reliable voltage monitoring.

Disadvantages

• Limited reset timeout period may not be suitable for certain applications requiring longer timeouts.
• Lack of additional features such as hysteresis or watchdog functionality.

Working Principles

ADM823RYRJZ-R7 works by comparing the input voltage with the set threshold voltage. When the input voltage drops below the threshold, the RESET pin outputs a low signal, indicating a reset condition. Once the voltage rises above the threshold, the RESET signal returns to its high state.

The reset timeout feature prevents continuous resetting by deactivating the RESET signal if the voltage remains below the threshold for a specific period.

Detailed Application Field Plans

ADM823RYRJZ-R7 finds applications in various electronic systems where voltage monitoring and reset functionality are critical. Some potential application fields include:

1. Microcontrollers and microprocessors
2. Power supply units
3. Industrial control systems
4. Automotive electronics
5. Battery-powered devices
