• Reset timeout period: 140ms (typical)
• Operating temperature range: -40°C to +85°C

Pin Configuration

ADM810ZARTZ-REEL7 has three pins:

1. VCC: Power supply input pin (+1.6V to +5.5V).
2. GND: Ground reference pin.
3. RESET: Output pin that provides a reset signal to the connected circuitry.

Functional Features

• Under-voltage detection: ADM810ZARTZ-REEL7 continuously monitors the supply voltage and detects when it falls below the specified threshold.
• Reset signal generation: When the voltage drops below the threshold, the device generates a reset signal to ensure proper functioning of the connected circuitry.
• Adjustable threshold: The threshold voltage can be selected from multiple options to suit different application requirements.
• Reset timeout: After power-up or voltage recovery, the reset signal remains active for a fixed period (140ms) to allow the system to stabilize before normal operation resumes.

Advantages and Disadvantages

Advantages

• Reliable voltage monitoring and reset functionality.
• Low power consumption.
• Compact package size for space-constrained designs.
• RoHS compliant, ensuring environmental compliance.

Disadvantages

• Limited threshold voltage options may not cover all application scenarios.
• Fixed reset timeout period may not be adjustable for specific requirements.

Working Principles

ADM810ZARTZ-REEL7 operates by comparing the supply voltage with the selected threshold voltage. When the supply voltage drops below the threshold, the internal circuitry triggers the generation of a reset signal. This signal remains active for a fixed timeout period, allowing the system to stabilize before resuming normal operation.
