Essence

The essence of ADM809ZART-REEL lies in its ability to monitor and control voltage levels, ensuring stable operation of electronic systems.

Packaging/Quantity

This product is typically packaged in reels containing a specific quantity, such as 3000 units per reel.

Specifications

• Supply voltage range: 1.2V to 5.5V
• Reset threshold voltage options: 2.93V, 3.08V, 3.15V, 4.38V, 4.63V
• Reset timeout period: 140ms (min)
• Quiescent current: 7µA (typical)

Detailed Pin Configuration

The ADM809ZART-REEL features three pins:

1. VCC: This pin is connected to the power supply voltage.
2. GND: This pin is connected to the ground reference.
3. RESET: This pin outputs a signal when the monitored voltage falls below the specified threshold.

Functional Features

• Voltage monitoring: The ADM809ZART-REEL continuously monitors the voltage level and triggers a reset signal when it falls below the threshold.
• Reset output: When the monitored voltage drops below the threshold, the RESET pin outputs a low signal to indicate a reset condition.
• Manual reset input: An external push-button can be connected to the MR (manual reset) pin to manually trigger a reset.

Advantages and Disadvantages

Advantages

• Reliable voltage supervision ensures stable operation of electronic systems.
• Low power consumption extends battery life in portable devices.
• Small package size allows for easy integration into compact designs.
• Wide operating temperature range enables usage in various environments.

Disadvantages

• Fixed voltage threshold may not be suitable for all applications requiring different thresholds.
• Lack of adjustable timeout period limits flexibility in certain scenarios.

Working Principles

The ADM809ZART-REEL operates by comparing the supply voltage with the fixed threshold voltage. If the supply voltage drops below the threshold, the internal circuitry triggers a reset signal. This signal remains active until the supply voltage rises above the threshold and the reset timeout period elapses.

Detailed Application Field Plans

The ADM809ZART-REEL finds applications in various fields, including but not limited to: 1. Battery-powered devices: Ensures proper functioning and prevents damage due to low voltage conditions. 2. Industrial control systems: Monitors voltage levels to prevent system failures and ensure reliable operation. 3. Automotive electronics: Protects sensitive components from voltage fluctuations and ensures safe operation. 4. Medical equipment: Provides voltage supervision to maintain the integrity of critical medical devices.
