```

---

| | --| VDD | --| /RESET| --| GND | --| N.C. | |_______| ```

Pin Description: - VDD: Supply voltage input - /RESET: Active low reset output - GND: Ground connection - N.C.: No connection (unused pin)

Functional Features

1. Voltage Detection: The S-80848CNMC-B89T2G can accurately detect the voltage level within the specified range.
2. Reset Function: When the detected voltage falls below the threshold, the /RESET pin outputs a low signal to initiate a reset.
3. Built-in Delay Circuit: The product includes a delay circuit that ensures a stable reset signal for 200ms (typ.) after the voltage rises above the threshold.

Advantages and Disadvantages

Advantages

• Wide voltage detection range allows for versatile applications.
• Low supply current minimizes power consumption.
• Small package size enables space-saving designs.
• Built-in delay circuit ensures reliable reset signals.

Disadvantages

• Limited reset threshold voltage options may not suit all applications.
• Active low output may require additional circuitry for certain systems.

Working Principles

The S-80848CNMC-B89T2G operates by continuously monitoring the input voltage. When the voltage falls below the preset threshold, the internal comparator triggers the reset function. The built-in delay circuit ensures a stable reset signal for a specific duration, allowing the system to properly initialize before resuming normal operation.

Detailed Application Field Plans

The S-80848CNMC-B89T2G finds applications in various electronic devices where voltage detection and reset functions are required. Some potential application fields include:

1. Microcontrollers: Ensuring proper initialization and system stability during power-up or brownout conditions.
2. Battery-Powered Devices: Monitoring battery voltage levels and triggering a reset when they drop below a certain threshold.
3. Industrial Control Systems: Providing reliable reset functionality for critical control units in industrial automation.
