Detailed Pin Configuration

The S-80944CLNB-G7ET2G 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
5. VOUT: Voltage detection output

Functional Features

1. Voltage Detection: The IC monitors the input voltage and compares it with the preset threshold voltage. When the input voltage falls below the threshold, the reset output is activated.
2. Delay Circuit: The built-in delay circuit ensures that the reset output remains active for a specific period after the input voltage rises above the threshold.
3. Manual Reset: The MR pin allows for manual resetting of the IC, overriding the automatic reset function.

Advantages and Disadvantages

Advantages

• Wide operating voltage range
• High accuracy in voltage detection
• Low supply current consumption
• Small package size for space-constrained applications
• Built-in delay circuit for reliable reset signal generation

Disadvantages

• Limited number of available threshold voltage options
• Active low reset output may not be suitable for all applications

Working Principles

The S-80944CLNB-G7ET2G operates based on a voltage divider network connected to the VDD pin. The internal comparator compares the divided voltage with the preset threshold voltage. When the input voltage drops below the threshold, the reset output is activated. The built-in delay circuit ensures that the reset output remains active for a specific time period after the input voltage rises above the threshold.

Detailed Application Field Plans
