Pin 1: VDD (Supply Voltage) Pin 2: GND (Ground) Pin 3: RESET (Output) Pin 4: N/C (No Connection) Pin 5: SENSE (Voltage Detection Input)

Functional Features

1. Voltage Detection: The S-80842CNNB-B83T2G accurately detects the voltage level applied to the SENSE pin within the specified range.
2. Reset Function: When the detected voltage falls below the threshold, the RESET pin is activated, providing a reset signal to the connected device.
3. Built-in Delay Circuit: The product incorporates a delay circuit that ensures a stable reset signal is provided for a specific duration (200ms typ.) after the voltage returns to the normal range.

Advantages and Disadvantages

Advantages

• Wide voltage detection range allows compatibility with various electronic devices.
• Low supply current minimizes power consumption.
• Small package size enables easy integration into space-constrained designs.
• Built-in delay circuit prevents false resets caused by temporary voltage fluctuations.

Disadvantages

• Limited output current may not be suitable for high-power applications.
• Noisy environments may affect the accuracy of voltage detection.

Working Principles

The S-80842CNNB-B83T2G operates based on a voltage divider network connected to the SENSE pin. When the applied voltage exceeds the threshold, the internal comparator activates the RESET pin, signaling a low output. The built-in delay circuit ensures a stable reset signal is maintained for a specific duration, even if the voltage fluctuates temporarily.
