4. VCC (Supply Voltage)
5. TH (Threshold Voltage Selection)
6. CT (Reset Timeout Period Selection)
7. NC (No Connection)
8. NC (No Connection)

Functional Features

• Monitors the power supply voltage and generates a reset signal when it falls below the selected threshold voltage.
• Provides an adjustable reset timeout period to ensure proper system initialization.
• Includes a manual reset input for external reset control.
• Low quiescent current consumption makes it suitable for battery-powered applications.
• Precision voltage reference ensures accurate monitoring.

Advantages

• Wide supply voltage range allows compatibility with various systems.
• Adjustable reset threshold and timeout period provide flexibility for different applications.
• Low quiescent current consumption helps conserve battery life.
• Small package size enables space-efficient designs.
• Accurate voltage monitoring ensures reliable system operation.

Disadvantages

• Limited number of available threshold voltage options.
• Reset timeout period is adjustable but has a maximum limit of 640ms.
• No internal pull-up or pull-down resistors on the MR pin, requiring external components for proper functionality.

Working Principles

The MAX806RCSA+T operates by continuously monitoring the supply voltage using an internal voltage reference. When the voltage falls below the selected threshold level, the reset output is activated, indicating a power failure or low voltage condition. The reset signal remains active until the voltage rises above the threshold level and the reset timeout period elapses.
