Functional Features

Voltage Detection

S-80945CLNB-G7FT2G can accurately detect the voltage level applied to its SENSE pin within the specified range of 1.6V to 5.0V.

Reset Function

When the detected voltage falls below the threshold, the RESET pin outputs a low signal, indicating the need for a system reset. This feature ensures reliable operation and prevents malfunctions caused by insufficient voltage levels.

Built-in Delay Circuit

The integrated delay circuit in S-80945CLNB-G7FT2G provides a stable reset signal with a delay time of approximately 200ms. This delay allows sufficient time for the system to stabilize before resuming normal operation.

Advantages and Disadvantages

Advantages

• Wide operating voltage range enables compatibility with various electronic devices.
• Low quiescent current minimizes power consumption.
• Small package size facilitates integration into space-constrained designs.
• Built-in delay circuit ensures stable operation during power fluctuations.

Working Principles

S-80945CLNB-G7FT2G operates based on a voltage divider network connected to the SENSE pin. When the applied voltage exceeds the threshold, the internal comparator triggers the RESET pin to output a high signal. Conversely, when the voltage falls below the threshold, the RESET pin outputs a low signal, indicating the need for a system reset.
