Detailed Pin Configuration

ADM809-5LAKSZ-REEL features a standard SOT-23-3 package with the following pin configuration:

1. VCC: Power supply input
2. GND: Ground reference
3. RESET: Output reset signal

Functional Features

• Voltage monitoring: ADM809-5LAKSZ-REEL continuously monitors the supply voltage to detect any drops below the specified threshold.
• Reset signal generation: When the voltage falls below the threshold, the device generates a reset signal to initiate system reset or other necessary actions.
• Reset timeout: The reset signal remains active for a specific period (140ms) after the voltage rises above the threshold, ensuring stable system operation.

Advantages and Disadvantages

Advantages

• Wide operating voltage range allows compatibility with various systems.
• Accurate reset threshold ensures reliable voltage monitoring.
• Low power consumption minimizes energy usage.
• Small package size enables use in space-constrained applications.
• Wide operating temperature range makes it suitable for harsh environments.

Disadvantages

• Lack of adjustable reset timeout period limits customization options.
• Limited reset threshold options may not cater to all voltage monitoring requirements.

Working Principles

ADM809-5LAKSZ-REEL operates based on a voltage comparator circuit. It compares the supply voltage against the preset threshold and generates a reset signal when the voltage falls below this threshold. The reset signal remains active for a specific duration, allowing the system to stabilize before resuming normal operation.

Detailed Application Field Plans

ADM809-5LAKSZ-REEL finds applications in various electronic systems where reliable voltage monitoring and reset functionality are crucial. Some potential application fields include:

1. Microcontrollers and microprocessors: Ensuring proper system initialization and preventing erratic behavior due to voltage fluctuations.
2. Communication devices: Maintaining stable operation by resetting the system in case of power supply issues.
3. Industrial control systems: Preventing data corruption or equipment malfunction caused by voltage drops.
4. Automotive electronics: Safeguarding critical components from voltage variations and ensuring reliable performance.
