Introducing the STM811SW16F Microprocessor Supervisor from STMicroelectronics

The STM811SW16F is a state-of-the-art microprocessor supervisory circuit designed and manufactured by STMicroelectronics, a global leader in semiconductor solutions. This compact, high-precision device is engineered to monitor the power supply and system health of microprocessor (μP) systems, ensuring that the system operates optimally under various conditions.

With its impressive feature set, the STM811SW16F provides critical protection to your microprocessor by performing three key functions: it acts as a reset controller, a watchdog timer, and a manual reset input facilitator. The device is particularly suitable for battery-powered applications due to its low power consumption and small footprint.

Key Features of STM811SW16F:

• Reset Output: The STM811SW16F has an active-low reset output, which remains asserted until the supply voltage reaches the reset threshold level and maintains stability for the reset active period.
• Watchdog Timer: This built-in watchdog timer keeps the system in check by forcing a system reset should the microprocessor fail to provide a periodic signal within a preset timeout period.
• Manual Reset Input: An additional manual reset input allows for an external trigger to initiate a system reset, providing an extra layer of control for system operators.
• Low Power Consumption: Designed for power-sensitive applications, the device operates with a quiescent current of just 3.0 μA, making it an energy-efficient choice for portable devices.
• High Accuracy: The STM811SW16F offers a reset threshold accuracy of ±1.5%, ensuring reliable operation and system stability.
• Operating Temperature Range: It is operational across a wide temperature range from -40°C to +85°C, suitable for harsh environments.

The STM811SW16F comes in a compact SOT-23 package, making it an ideal choice for space-constrained applications. Its robust design ensures that your microprocessor system is safeguarded against power supply glitches, brown-out conditions, and system malfunctions that could lead to data loss or corruption.

Whether you're designing a portable device, an automotive system, or a complex digital appliance, the STM811SW16F from STMicroelectronics provides the reliability and performance you need to ensure your product operates safely and effectively.
