Detailed Pin Configuration

The S-80849CNY-B-G IC has the following pin configuration:

1. VDD: Supply voltage input
2. GND: Ground reference
3. RESET: Active low reset output
4. MR: Manual reset input (optional)
5. VOUT: Voltage detection output

Functional Features

1. Voltage Detection: The IC accurately detects the input voltage level within the specified range.
2. Reset Signal Generation: When the detected voltage falls below the preset threshold, the IC generates an active low reset signal.
3. Manual Reset (MR) Input: An optional manual reset input allows for external control of the reset function.

Advantages and Disadvantages

Advantages

• Wide voltage detection range
• Low supply current consumption
• Accurate voltage detection with ±2% accuracy
• Compact SOT-23-5 package for space-constrained applications

Disadvantages

• Limited options for reset threshold voltages
• Lack of built-in hysteresis for noise immunity

Working Principles

The S-80849CNY-B-G IC operates by comparing the input voltage with the preset threshold voltage. When the input voltage falls below the threshold, the IC triggers the reset signal, indicating a power-on reset or voltage drop event. The manual reset input allows for additional control over the reset function.
