2. GND: Ground reference pin.
3. RESET: Output pin for reset signal.

Functional Features

Voltage Monitoring

ADM809MAKS-REEL7 continuously monitors the supply voltage and compares it with the preset threshold voltage. When the supply voltage drops below the threshold, the reset output is activated.

Reset Signal

The reset output pin provides an active-low reset signal to the system, indicating that the supply voltage has fallen below the threshold.

Precision Monitoring

This IC offers precise voltage monitoring, ensuring accurate detection of voltage variations.

Advantages and Disadvantages

Advantages

• Low power consumption makes it suitable for battery-powered applications.
• Wide operating voltage range allows compatibility with various systems.
• Small package size enables space-saving designs.

Disadvantages

• Limited threshold voltage options may not cater to all voltage monitoring requirements.
• Reset timeout period may not be adjustable, limiting flexibility in certain applications.

Working Principles

ADM809MAKS-REEL7 operates by comparing the supply voltage with the preset threshold voltage. When the supply voltage drops below the threshold, the reset output is activated, indicating a power failure or voltage drop.
