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

Pin 1: GND (Ground) Pin 2: VDD (Supply Voltage) Pin 3: RESET (Output) Pin 4: N/C (No Connection) Pin 5: VDET (Voltage Detection Input)

Functional Features

• Voltage detection: The S-80857CLPF-B7ITFG can accurately detect the input voltage within the range of 1.2V to 6.0V.
• Reset function: When the input voltage drops below the detection threshold, the RESET pin is activated, providing a low output signal.
• Delay circuit: The built-in delay circuit ensures a stable output after the voltage returns to the normal range.

Advantages and Disadvantages

Advantages

• Wide voltage detection range allows for versatile applications.
• Low supply current minimizes power consumption.
• High accuracy voltage detection threshold ensures reliable operation.
• Small package size enables space-saving designs.
• RoHS compliance promotes environmental friendliness.

Disadvantages

• Limited to open-drain output configuration.
• No internal pull-up resistor, requiring an external pull-up resistor for certain applications.

Working Principles

The S-80857CLPF-B7ITFG operates based on a voltage divider network connected to the VDET pin. When the input voltage exceeds the detection threshold, the internal comparator activates the RESET pin, pulling it low. This indicates a reset condition in the system. The delay circuit ensures that the output remains stable during voltage fluctuations.

Detailed Application Field Plans

The S-80857CLPF-B7ITFG finds applications in various electronic devices where voltage monitoring and reset functions are required. Some potential application fields include:

1. Battery-powered devices: Ensuring proper operation by monitoring battery voltage and initiating a reset when necessary.
2. Microcontrollers: Providing a reset signal to restart the microcontroller in case of power supply issues.
3. Power management systems: Monitoring voltage levels to protect sensitive components from overvoltage or undervoltage conditions.
