Functional Features

1. Voltage Detection: The S-80941CNNB-G9BT2G can accurately detect voltage levels within the specified range.
2. Reset Signal Generation: When the detected voltage falls below the threshold, the device generates a reset signal.
3. Manual Reset: The MR pin allows for manual reset input, providing flexibility in system control.

Advantages and Disadvantages

Advantages

• Wide voltage detection range enables compatibility with various applications.
• Low supply current minimizes power consumption.
• Small package size facilitates integration into space-constrained designs.
• Accurate reset threshold ensures reliable system operation.

Disadvantages

• Manual reset feature may not be necessary in all scenarios.

Working Principles

The S-80941CNNB-G9BT2G operates based on a voltage divider network connected to the VOUT pin. When the voltage at VOUT falls below the preset threshold, the RESET pin is activated, generating a reset signal. The delay circuit ensures a stable output by introducing a 200ms delay before the reset signal is released.
