STM817LM6E

STM817LM6E Description

The STM817LM6E is a single-channel voltage supervisor IC designed by STMicroelectronics. This device is engineered to monitor a single voltage input and provide a reliable reset signal to microcontrollers or other digital systems when the monitored voltage falls below a predefined threshold. The STM817LM6E is housed in an 8SO package and is suitable for surface-mount applications, making it ideal for compact and high-density PCB designs.

STM817LM6E Features

• Voltage Monitoring: The STM817LM6E is designed to monitor a single voltage input with a threshold voltage of 4.65V. This precise threshold ensures accurate detection of under-voltage conditions, safeguarding the system from potential damage due to insufficient power supply levels.
• Reset Functionality: The reset output of the STM817LM6E is active low, providing a clear and reliable signal to reset the system when the monitored voltage drops below the threshold. The reset timeout is a minimum of 140ms, ensuring sufficient time for the system to stabilize before reinitialization.
• Packaging and Mounting: The device comes in a tube package, which is ideal for bulk handling and automated assembly processes. The surface-mount mounting type allows for efficient use of PCB space and enhanced thermal performance.
• Compliance and Standards: The STM817LM6E is REACH unaffected and ROHS3 compliant, ensuring it meets the stringent environmental and safety standards required by modern electronics manufacturing. Additionally, it has a moisture sensitivity level (MSL) of 1, indicating it is suitable for unlimited exposure to standard environmental conditions.
• Obsolete Status: While the STM817LM6E is marked as obsolete, it remains a viable option for legacy systems and applications where its specific features and performance characteristics are still required.

STM817LM6E Applications

The STM817LM6E is well-suited for a variety of applications where reliable voltage monitoring and system reset are critical. Some specific use cases include:

• Embedded Systems: In embedded systems, the STM817LM6E can be used to monitor the power supply voltage of microcontrollers, ensuring they operate within safe voltage levels and preventing erratic behavior or damage due to under-voltage conditions.
• Power Management: For power management applications, the STM817LM6E provides a straightforward and effective solution for monitoring the main power supply voltage and initiating a reset if the voltage drops below the threshold, thereby maintaining system stability and reliability.
• Industrial Control: In industrial control systems, where equipment reliability is paramount, the STM817LM6E can be integrated to monitor critical power supplies and ensure that control systems are reset appropriately in the event of power fluctuations or failures.
