Pin 1: VCC - Power supply input
Pin 2: RESET - Reset output

Functional Features

• Voltage monitoring: ADM812ZARTZ-REEL continuously monitors the power supply voltage.
• Reset signal generation: When the voltage drops below the specified threshold, the IC generates a reset signal to ensure proper system operation.
• Adjustable threshold: The threshold voltage can be selected from various options to suit different application requirements.
• Reset timeout: The IC provides a programmable reset timeout period to prevent false resets during temporary voltage fluctuations.

Advantages and Disadvantages

Advantages

• Reliable voltage monitoring and reset functionality.
• Low power consumption.
• Compact package size for space-constrained designs.
• Wide operating voltage range.
• Adjustable threshold voltage and reset timeout options.

Disadvantages
