It is used to monitor the power supply voltage and reset the system when the voltage falls below a certain threshold.

Characteristics

• Voltage monitoring range: 1.8V to 5.5V
• Adjustable reset threshold voltage
• Low quiescent current consumption
• Small package size (SOT-23-3)
• RoHS compliant

Package

ADM823SYKSZ-R7 is available in a SOT-23-3 package.

Essence

The essence of ADM823SYKSZ-R7 is to provide reliable voltage monitoring and reset functionality for electronic systems.

Packaging/Quantity

It is typically sold in reels containing 3000 units per reel.

Specifications

• Supply Voltage Range: 1.8V to 5.5V
• Reset Threshold Voltage Range: 1.6V to 4.63V
• Quiescent Current: 2.5µA (typical)
• Operating Temperature Range: -40°C to +85°C

Detailed Pin Configuration

ADM823SYKSZ-R7 has three pins:

1. VCC: Power supply input pin.
2. GND: Ground reference pin.
3. RESET: Output pin that goes low when the monitored voltage drops below the threshold.

Functional Features

• Monitors the power supply voltage continuously.
• Resets the system when the voltage falls below the set threshold.
• Adjustable reset threshold voltage allows customization for different applications.
• Low quiescent current consumption minimizes power consumption.
• Provides a reliable reset signal to ensure proper system operation.

Advantages and Disadvantages

Advantages

• Wide operating voltage range allows compatibility with various systems.
• Adjustable reset threshold voltage provides flexibility.
• Low quiescent current consumption helps conserve power.
• Small package size enables space-saving designs.
• RoHS compliance ensures environmental friendliness.

Disadvantages

• Limited to voltage monitoring and reset functionality only.
• Not suitable for applications requiring more advanced supervision features.

Working Principles

ADM823SYKSZ-R7 works by continuously monitoring the power supply voltage. When the voltage drops below the set threshold, the RESET pin goes low, indicating a system reset. The reset condition persists until the voltage rises above the threshold again.
