| | --|----|-- |____| ```

Pin 1: VDD (Supply voltage) Pin 2: GND (Ground) Pin 3: RESET (Output reset signal) Pin 4: SENSE (Voltage detection input) Pin 5: NC (No connection)

Functional Features

• Voltage Detection: The S-80859CLPF-B7KTFG can accurately detect the voltage level applied to the SENSE pin within the specified range.
• Reset Function: When the detected voltage falls below a certain threshold, the RESET pin outputs a low signal, indicating the need for a system reset.
• Delay Circuit: The built-in delay circuit ensures a stable output by delaying the reset signal for a fixed period of time (200ms typ.) after the voltage returns to the normal range.

Advantages and Disadvantages

Advantages

• Wide voltage detection range allows compatibility with various electronic devices.
• High accuracy voltage detection ensures reliable operation.
• Low quiescent current minimizes power consumption.
• Compact package size enables easy integration into space-constrained designs.

Disadvantages

• Limited to voltage detection and reset functions, may not suit applications requiring more complex features.
• Not suitable for high-voltage applications above 6.0V.

Working Principles

The S-80859CLPF-B7KTFG operates based on a voltage divider network connected to the SENSE pin. When the applied voltage exceeds the detection threshold, the internal comparator triggers the RESET pin to output a low signal, indicating the need for a system reset. The delay circuit ensures a stable reset signal by introducing a fixed delay before activating the RESET pin.

Detailed Application Field Plans

The S-80859CLPF-B7KTFG finds application in various electronic devices where voltage monitoring and reset functionality are crucial. Some potential application fields include:

1. Battery-Powered Devices: Ensures proper shutdown and protection when battery voltage drops below a certain level.
2. Microcontrollers: Provides a reliable reset signal to ensure proper initialization and operation.
3. Power Management Systems: Monitors voltage levels to prevent damage to sensitive components during power fluctuations.
4. Industrial Control Systems: Enables safe system reset in case of voltage anomalies, ensuring uninterrupted operation.
