1. VDD: Supply voltage input
2. GND: Ground reference
3. RESET: Active low reset output
4. MR: Manual reset input (optional)
5. NC: No connection

Functional Features

1. Voltage Detection: The S-80816CLUA-B6BT2U accurately detects the supply voltage within the specified range.
2. Reset Signal Generation: When the supply voltage falls below the threshold level, the active low reset signal is generated on the RESET pin.
3. Delay Circuit: The built-in delay circuit ensures a stable reset signal by introducing a delay of approximately 200ms.

Advantages and Disadvantages

Advantages

• Wide voltage detection range
• High accuracy
• Low quiescent current consumption
• Compact package size
• Built-in delay circuit for stable reset signal generation

Disadvantages

• Limited options for manual reset functionality
