Functional Features

Voltage Detection

The S-80942CNPF-G9CTFG can accurately detect the voltage level applied to its VIN pin within the specified range of 1.0V to 6.0V. This feature enables precise monitoring of the power supply voltage in electronic systems.

Reset Function

When the detected voltage falls below the threshold set by the device, the S-80942CNPF-G9CTFG generates a reset signal on its RESET pin. This functionality ensures proper system initialization and prevents erratic behavior caused by insufficient voltage levels.

Low Power Consumption

With a quiescent current of only 1.0µA (typical), the S-80942CNPF-G9CTFG minimizes power consumption, making it suitable for battery-powered applications where energy efficiency is crucial.

Advantages and Disadvantages

Advantages

• Wide voltage detection range
• Accurate voltage detection with low tolerance
• Low power consumption
