STM813LM6E Description

The STM813LM6E is a single-channel voltage supervisor IC designed by STMicroelectronics, a leading manufacturer in the electronics industry. This IC is part of the Power Management (PMIC) category and is housed in an 8SO package. Despite being marked as obsolete, the STM813LM6E remains a reliable solution for applications requiring precise voltage monitoring and reset functionality.

STM813LM6E Features

• Voltage Monitoring: The STM813LM6E is designed to monitor a single voltage level, ensuring that it remains above the threshold of 4.63V. This precise threshold is crucial for maintaining system stability and preventing unexpected shutdowns due to voltage fluctuations.
• Reset Functionality: The IC features an active-high reset output, which is triggered when the monitored voltage falls below the threshold. The reset timeout is a minimum of 140ms, providing ample time for the system to stabilize before reinitializing.
• Surface Mount Technology: The STM813LM6E is available in a surface mount package, making it suitable for modern, space-efficient PCB designs. This mounting type ensures robustness and ease of integration into various electronic systems.
• Compliance and Standards: The STM813LM6E adheres to stringent industry standards, including REACH (Registration, Evaluation, Authorization, and Restriction of Chemicals) and RoHS (Restriction of Hazardous Substances) compliance. It is classified under ECCN (Export Control Classification Number) EAR99 and HTSUS (Harmonized Tariff Schedule of the United States) code 8542.39.0001.
• Moisture Sensitivity Level: The MSL (Moisture Sensitivity Level) is rated at 1 (Unlimited), indicating that the IC is highly resistant to moisture, making it suitable for a wide range of environmental conditions.

STM813LM6E Applications

The STM813LM6E is ideal for applications where reliable voltage monitoring and reset functions are essential. Some specific use cases include:

• Power Supplies: Ensuring stable operation of power supplies by monitoring the input voltage and providing a reset signal if the voltage drops below the threshold.
• Embedded Systems: Protecting embedded systems from voltage sags and brownouts, thereby maintaining system integrity and preventing data loss.
• Industrial Control Systems: Monitoring power levels in industrial control systems to prevent malfunctions and ensure continuous operation.
• Telecommunications Equipment: Providing voltage supervision in telecom equipment to maintain reliable communication links.

Conclusion of STM813LM6E

The STM813LM6E, despite its obsolete status, remains a robust solution for voltage monitoring and reset functions in various electronic systems. Its precise voltage threshold, reliable reset timeout, and surface mount packaging make it a versatile component. Compliance with industry standards and its high moisture sensitivity level further enhance its suitability for diverse applications. While newer alternatives may be available, the STM813LM6E continues to offer reliable performance for applications where single-channel voltage supervision is required.
