Overview of STM811TW16F Microprocessor Supervisor

The STM811TW16F from STMicroelectronics is a compact, low-power microprocessor supervisory circuit designed to monitor power supply and system health in digital systems. It provides a crucial safeguard for microprocessors and digital systems by resetting these systems during power-up, power-down, and brown-out conditions. This ensures that the system starts in a known state every time.

Key Features

• Precision Monitoring: The STM811TW16F offers precise monitoring of the 1.6V power supply voltage with a tight accuracy of ±1.5%, which is essential for ensuring reliable operation of digital circuits that are sensitive to voltage variations.
• Low Power Consumption: Designed for power-sensitive applications, this device consumes a minimal amount of power, with a typical supply current of only 3µA, making it an ideal choice for battery-operated systems.
• Manual Reset Input: The inclusion of a manual reset input provides an additional layer of system control, allowing users to manually trigger a system reset when necessary.
• Reset Time Delay: The device features a 140ms minimum reset pulse width, which ensures that the system has sufficient time to stabilize after a reset event before resuming operation.
• Operating Temperature Range: The STM811TW16F is designed to operate over a wide temperature range from -40°C to +85°C, making it suitable for various industrial and consumer applications.
• Small Package: It is available in a compact SOT-23 5-lead package, which minimizes the footprint on the PCB and is convenient for space-constrained applications.
