2. RESET: Output reset signal
3. MR: Manual reset input
4. VDD: Supply voltage input
5. NC: No connection

Functional Features

Voltage Monitoring

The MIC812RUY-TR continuously monitors the supply voltage and compares it to a preset threshold. If the voltage falls below the threshold, the reset output is activated.

Reset Signal Generation

When the supply voltage drops below the specified threshold, the MIC812RUY-TR generates a reset signal. This signal can be used to reset microcontrollers, CPUs, or other critical components in the system.

Manual Reset Input

The MR pin allows for manual reset control. When this pin is pulled low, the reset signal is activated, regardless of the supply voltage level.

Advantages and Disadvantages

Advantages

• Reliable voltage monitoring and reset functionality
• Low power consumption
• Compact package size
• Wide operating temperature range

Disadvantages

• Limited reset threshold and timeout period options
• Lack of additional advanced features

Working Principles

The MIC812RUY-TR operates by comparing the supply voltage with a preset threshold. When the voltage drops below the threshold, the internal circuitry triggers the reset signal. The manual reset input provides an additional means of activating the reset signal.
