1. RESET: Reset Output
2. GND: Ground
3. MR: Manual Reset Input
4. VCC: Supply Voltage
5. RESET: Reset Output

Functional Features

• Monitors supply voltage and generates a reset signal when voltage falls below the threshold.
• Provides a manual reset input for immediate system reset.
• Offers multiple options for reset threshold voltage and timeout period.

Advantages

• Low power consumption makes it suitable for battery-powered applications.
• Small package size allows for space-efficient designs.
