Detailed Pin Configuration

The S-80923CNMC-G8TT2G has a total of five pins, which are assigned specific functions:

1. VDD: Supply voltage input
2. GND: Ground reference
3. RESET: Active low reset output
4. SENSE: Voltage detection pin
5. NRST: No connection (NC)

Functional Features

• Accurate voltage detection: The S-80923CNMC-G8TT2G can detect voltage levels within the specified range with high accuracy, ensuring reliable operation of electronic systems.
• Reset signal generation: When the detected voltage falls below the preset threshold, the IC generates an active low reset signal, allowing for proper system initialization or shutdown.
• Built-in delay circuit: The integrated delay circuit ensures a stable reset signal is provided after the voltage returns to the normal operating range, preventing false resets during transient voltage fluctuations.

Advantages and Disadvantages

Advantages

• Wide voltage detection range
• High accuracy
• Low supply current consumption
• Compact package size
• Built-in delay circuit for stable reset signals

Disadvantages

• Limited options for reset threshold voltage and delay time

Working Principles

The S-80923CNMC-G8TT2G operates based on a voltage divider network connected to the SENSE pin. When the voltage at the SENSE pin drops below the preset threshold, the internal comparator triggers the reset output to go low. The built-in delay circuit ensures that the reset signal remains low for a specific duration, even if the voltage at the SENSE pin momentarily recovers.

Detailed Application Field Plans

The S-80923CNMC-G8TT2G finds applications in various electronic devices where accurate voltage detection and reset functionality are required. Some potential application fields include:

1. Microcontrollers: Ensuring proper initialization and safe shutdown of microcontroller-based systems.
2. Power management systems: Monitoring power supply voltages and triggering appropriate actions in case of voltage abnormalities.
3. Battery-powered devices: Preventing damage to sensitive electronics by initiating a controlled shutdown when battery voltage drops below a certain level.
4. Industrial automation: Providing reliable reset signals for PLCs (Programmable Logic Controllers) and other control systems.
