Pin 1: GND (Ground) Pin 2: VDD (Supply Voltage) Pin 3: RESET (Reset Output) Pin 4: VIN (Input Voltage) Pin 5: NC (No Connection)

Functional Features

1. Voltage Detection: The S-80857CNMC-B9IT2G accurately detects the input voltage within the specified range.
2. Reset Function: When the input voltage falls below the detection threshold, the reset output is activated, providing a signal to reset the device.
3. Low Power Consumption: With a quiescent current of only 1.0μA, this IC minimizes power consumption in electronic devices.

Advantages and Disadvantages

Advantages

• Wide voltage detection range allows for versatile applications.
• Accurate voltage detection with low tolerance ensures reliable performance.
• Small package size enables space-saving designs.
• Low power consumption prolongs battery life in portable devices.

Disadvantages

• Limited to N-channel open drain reset output type.
• Not suitable for applications requiring higher output currents.

Working Principles

The S-80857CNMC-B9IT2G operates based on a voltage divider network connected to the VIN pin. When the input voltage exceeds the detection threshold, the internal comparator activates the reset output, signaling a high or low state depending on the open-drain configuration.
