Pin 1: VDD (Supply voltage) Pin 2: GND (Ground) Pin 3: MR (Manual reset input) Pin 4: VOUT (Output voltage) Pin 5: SENSE (Voltage detection input)

Functional Features

1. Voltage Detection: The S-80940CNPF-G9ATFU accurately detects the input voltage level within the specified range.
2. Reset Function: When the detected voltage falls below the set threshold, the IC generates a reset signal to ensure proper device operation.
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
• Accurate voltage detection with low tolerance
• Low power consumption
• Small package size for space-constrained applications

Disadvantages

• Limited output current capacity (10mA maximum)
• Requires an external manual reset input (MR pin)

Working Principles

The S-80940CNPF-G9ATFU operates based on a voltage divider network connected to the SENSE pin. When the input voltage exceeds the set threshold, the internal comparator triggers the output to remain high. However, if the voltage drops below the threshold, the output is pulled low, generating a reset signal.

Detailed Application Field Plans

The S-80940CNPF-G9ATFU finds application in various electronic devices that require voltage monitoring and reset functionality. Some potential application fields include:

1. Microcontrollers: Ensuring reliable operation by resetting the microcontroller when the supply voltage drops below a certain level.
2. Battery-Powered Devices: Preventing damage to batteries by initiating a shutdown or warning when the battery voltage reaches a critical level.
3. Industrial Control Systems: Monitoring power supply voltages in control systems to prevent malfunctions or data corruption during voltage fluctuations.

Detailed and Complete Alternative Models

1. S-80940CNPF-G9ATFJ: Similar to S-80940CNPF-G9ATFU, but with a different package (SOT-89-5).
2. S-80940CNPF-G9ATFG: Similar to S-80940CNPF-G9ATFU, but with a different detection voltage range (0.9V to 5.5V).

These alternative models offer similar functionality and can be considered as substitutes for the S-80940CNPF-G9ATFU in various applications.
