Functional Features

Voltage Detection

S-80918CNNB-G8NT2G accurately detects the voltage level applied to its input pin within the specified range. It provides a reliable indication of the power supply voltage.

Reset Function

When the detected voltage falls below the preset threshold, the S-80918CNNB-G8NT2G generates an active low reset signal. This signal can be used to initiate system resets or trigger specific actions in electronic devices.

Manual Reset (MR) Input (optional)

The S-80918CNNB-G8NT2G offers an optional manual reset input pin. When this pin is pulled low, it forces the reset output to go low, regardless of the voltage level at the detection input pin.

Advantages and Disadvantages

Advantages

• Wide voltage detection range allows compatibility with various power supply systems.
• High accuracy ensures precise voltage detection.
• Low quiescent current minimizes power consumption.
• Small package size enables easy integration into space-constrained designs.
• RoHS compliance promotes environmental friendliness.

Disadvantages

• Limited number of available reset threshold voltage options.
• Lack of built-in hysteresis may result in potential oscillations near the threshold voltage.

Working Principles

The S-80918CNNB-G8NT2G operates based on a voltage divider network connected to the detection input pin. The internal comparator compares the divided voltage with the preset threshold voltage. When the detected voltage falls below the threshold, the reset output is activated.
