Description

The S-80841CNNB-G is a voltage detector IC manufactured by SII Semiconductor Corporation. This device is designed to monitor the supply voltage and generate a reset signal when the voltage drops below a certain threshold. Its primary function is to prevent malfunctions caused by unstable voltage levels, ensuring the reliable operation of electronic systems.

Applications

  • Microcontroller Reset Circuits: It's commonly used to provide a reliable reset signal to microcontrollers during power-up or brown-out conditions, preventing them from operating with insufficient voltage.
  • CPU Reset Circuits: Similar to microcontroller applications, it ensures that CPUs start in a defined state and avoid data corruption when power is initially applied or when voltage fluctuations occur.
  • Power Supply Monitoring: The device monitors the output voltage of power supplies, triggering an alarm or shutdown if the voltage deviates from the specified range. This helps prevent damage to connected devices.
  • Battery-Powered Devices: In battery-operated systems, it safeguards against deep discharge by shutting down the device when the battery voltage drops to a critical level, thus extending battery lifespan.
  • Industrial Control Systems: It is utilized to monitor voltage levels in industrial equipment, providing a layer of protection against damage due to voltage instability.

Features

  • Low Voltage Detection: The device accurately detects when the input voltage falls below a preset threshold (likely 4.1V based on the '41' in the part number).
  • High-Precision Detection Voltage: It offers a precise voltage detection threshold, ensuring reliable voltage monitoring.
  • Low Current Consumption: The design minimizes power consumption, making it suitable for use in battery-powered and energy-conscious applications.
  • Built-in Hysteresis: Hysteresis is implemented to prevent oscillations or false triggering around the threshold voltage.
  • Open-Drain Output: Typically features an open-drain output, offering flexibility in connecting to different logic circuits.

Benefits

  • Improved System Reliability: By resetting the system during voltage drops, the device prevents malfunctions and enhances the overall system reliability.
  • Data Protection: It protects data by initiating a controlled shutdown during power failures, minimizing the risk of data corruption.
  • Extended Battery Life: The low current consumption contributes to longer battery life in portable devices.
  • Simplified Circuit Design: Integration of the voltage detection function simplifies the design process and reduces the number of components needed.
  • Cost-Effective: It provides a cost-effective solution for voltage monitoring and reset generation in electronic systems.

Additional Details

The S-80841 series voltage detectors are available in various package types. The specific threshold voltage is determined by the part number (4.1V in this case, based on the name). The 'G' likely denotes a specific manufacturing code or packaging option. The output configuration usually involves an open-drain NMOS transistor that requires an external pull-up resistor. These devices operate over a wide temperature range, typically from -40°C to +85°C.
