Characteristics

• Voltage monitoring: ADM824SYRJZ-REEL7 is designed to monitor the voltage level of a power supply and provide a reset signal when the voltage falls below a certain threshold.
• Reset function: It ensures that the microcontroller or other digital circuitry starts in a known state after power-up or voltage fluctuations.
• Package: ADM824SYRJZ-REEL7 is available in a small outline integrated circuit (SOIC) package.
• Essence: The essence of this product lies in its ability to provide reliable voltage monitoring and reset functionality in various electronic applications.
• Packaging/Quantity: ADM824SYRJZ-REEL7 is typically packaged in reels containing a specific quantity of ICs.

Specifications

• Supply Voltage Range: 1.6V to 5.5V
• Threshold Voltage Options: 2.32V, 2.93V, 3.08V, 4.38V
• Reset Timeout Period: 140ms, 560ms, 1120ms, 2240ms
• Operating Temperature Range: -40°C to +85°C

Detailed Pin Configuration

ADM824SYRJZ-REEL7 has the following pin configuration:

1. VCC: Power supply input
2. GND: Ground reference
3. MR: Manual reset input
4. RESET: Reset output

Functional Features

• Voltage Monitoring: ADM824SYRJZ-REEL7 continuously monitors the supply voltage and compares it with the preset threshold voltage.
• Reset Generation: When the supply voltage falls below the threshold, ADM824SYRJZ-REEL7 asserts the reset output, ensuring a controlled reset of the connected circuitry.
• Manual Reset: The MR pin allows for manual reset control, overriding the automatic reset function.

Advantages and Disadvantages

Advantages

• Reliable voltage monitoring and reset functionality
• Wide supply voltage range allows for versatile applications
• Multiple threshold voltage and timeout period options provide flexibility
• Small package size enables space-efficient designs

Disadvantages

• Limited to voltage monitoring and reset functions only
• Requires external components for proper operation

Working Principles

ADM824SYRJZ-REEL7 operates by continuously comparing the supply voltage with the preset threshold voltage. When the supply voltage drops below the threshold, the reset output is asserted, initiating a reset sequence. The reset remains active until the supply voltage rises above the threshold or a manual reset signal is received.

Detailed Application Field Plans

ADM824SYRJZ-REEL7 finds application in various electronic devices where reliable voltage monitoring and reset functionality are crucial. Some potential application fields include:

1. Microcontrollers: Ensuring a controlled startup and reset state for microcontroller-based systems.
2. Embedded Systems: Providing voltage monitoring and reset capabilities in embedded systems for enhanced reliability.
3. Power Supplies: Safeguarding power supply circuits by detecting low voltage conditions and triggering appropriate actions.
4. Industrial Control Systems: Maintaining stable operation of industrial control systems by monitoring power supply integrity.
