Functional Features

1. Voltage Detection: The S-80945CNMC-G9FT2U can accurately detect voltage levels within the specified range.
2. Reset Function: It provides a reset signal through the open-drain output when the detected voltage falls below the threshold.
3. Manual Reset: The MR pin allows for manual reset control, overriding the automatic detection.

Advantages and Disadvantages

Advantages

• Wide voltage detection range
• Low supply current consumption
• Small package size for space-constrained applications
• Accurate voltage detection with low detection voltage deviation

Disadvantages

• Limited number of pins for additional functionalities
• Lack of built-in hysteresis for voltage detection

Working Principles

The S-80945CNMC-G9FT2U operates by comparing the input voltage at the SENSE pin with an internal reference voltage. When the input voltage falls below the detection threshold, the reset output is activated, indicating a low-voltage condition. The MR pin can be used to manually reset the device, regardless of the voltage level.
