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

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

Functional Features

• Voltage detection: The IC monitors the input voltage and compares it to a reference voltage, triggering the reset output when the voltage falls below a certain threshold.
• Reset signal generation: When the input voltage drops below the detection threshold, the IC generates a reset signal to initiate system reset or other necessary actions.
• Delay circuit: The built-in delay circuit ensures that the reset signal remains active for a specified duration (typically 200ms) 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 ensures reliable voltage detection.
• Small package size enables space-saving designs.

Disadvantages

• Open-drain output may require additional components for certain applications.
• Limited pin configuration options may restrict flexibility in circuit design.

Working Principles

The S-80859CLUA-B7KT2U operates by comparing the input voltage (VIN) with an internal reference voltage. When the input voltage falls below the detection threshold, the IC generates a reset signal on the RESET pin. This signal remains active for a specified delay period, allowing the system to perform necessary actions during this time. Once the input voltage rises above the threshold, the reset signal is deactivated.

Detailed Application Field Plans

The S-80859CLUA-B7KT2U finds application in various electronic devices where voltage monitoring and reset functionality are required. Some potential application fields include:

1. Microcontrollers: Ensuring proper system initialization and recovery after power fluctuations.
2. Battery-powered devices: Preventing damage due to undervoltage conditions and facilitating safe shutdown procedures.
3. Industrial control systems: Providing reliable reset signals for critical processes and equipment.
4. Automotive electronics: Monitoring battery voltage and initiating appropriate actions to prevent battery drain or system malfunction.
