The SGM706-TYS8G/TR is a supervisory circuit manufactured by SG Micro Corp. It's designed to monitor the voltage levels of power supplies in electronic systems and provide a reset signal when a voltage fault occurs. This ensures that the system starts up correctly and operates reliably by preventing erratic behavior due to insufficient or unstable power.

Applications

• Microcontroller-Based Systems: Resets the microcontroller upon power-up or voltage dips to ensure proper operation.
• Digital Signal Processors (DSPs): Monitors the power supply of DSPs to prevent data corruption and system crashes.
• FPGA-Based Systems: Supervises the power rails of FPGAs for reliable configuration and operation.
• Memory Systems: Protects memory contents by generating a reset during power failures or voltage fluctuations.
• Industrial Control Systems: Monitors power supplies in industrial equipment to prevent malfunctions and ensure safety.

Features

• Precision Voltage Monitoring: Accurately monitors the input voltage against a pre-defined threshold.
• Adjustable Reset Timeout: Allows customization of the reset pulse width to accommodate different system requirements.
• Open-Drain Output: Provides flexibility in connecting the reset output to various microcontroller and processor inputs.
• Low Supply Current: Minimizes power consumption, making it suitable for battery-powered applications.
• Small Package: Available in a compact package for space-constrained applications.
• Temperature Range: Wide operating temperature range for use in various environments.

Benefits

• Improved System Reliability: Prevents erroneous operation and data corruption caused by voltage faults.
• Simplified System Design: Reduces the need for external components and complex reset circuitry.
• Lower Power Consumption: Minimizes power drain in battery-powered devices.
• Increased System Robustness: Protects against voltage fluctuations and power failures.
• Reduced Development Time: Simplifies the design and implementation of reset functionality.

Additional Details

The SGM706-TYS8G/TR monitors a single voltage level and asserts a reset signal when the voltage falls below the specified threshold. The reset output remains asserted for a defined timeout period after the voltage recovers above the threshold. This ensures that the system has sufficient time to stabilize before normal operation resumes. The reset timeout can be adjusted using an external capacitor, allowing for customization based on the system's specific requirements. The open-drain output can be connected to the reset input of a microcontroller or processor with a pull-up resistor. The device operates with a low supply current, making it ideal for battery-powered applications where power conservation is critical. The compact package allows for easy integration into space-constrained designs. The wide operating temperature range enables reliable operation in industrial and automotive environments.
