MN1381-J

MN1381-J Description

The MN1381-J is a single-channel supervisor IC designed by Panasonic Electronic Components, renowned for its reliability and precision in power monitoring applications. This Through Hole mounted IC is housed in a TO92 package, making it suitable for a wide range of electronic systems. Despite being marked as obsolete, the MN1381-J remains a valuable component for legacy systems and specific applications where its unique features are required.

MN1381-J Features

• Single Voltage Monitoring: The MN1381-J is designed to monitor a single voltage, ensuring that the system operates within a safe and reliable threshold. The voltage threshold is set at 2.6V, providing a precise monitoring point for critical power supply levels.
• Active High Reset: The reset function of the MN1381-J is active high, which means it asserts a reset signal when the monitored voltage falls below the threshold. This feature is crucial for maintaining system stability and preventing erratic behavior during power fluctuations.
• Typical Reset Timeout of 115µs: The reset timeout of 115µs ensures that the system has sufficient time to stabilize after a power event, preventing premature reset and ensuring reliable operation.
• Bulk Packaging: The MN1381-J is available in bulk packaging, making it convenient for large-scale production and assembly processes.
• Moisture Sensitivity Level (MSL) 1: With an MSL rating of 1, the MN1381-J is classified as unlimited in terms of moisture sensitivity, making it suitable for storage and handling in various environmental conditions without the need for special precautions.
• ECCN Classification (EAR99): The Export Control Classification Number (ECCN) of EAR99 indicates that the MN1381-J is not subject to specific export controls, simplifying international distribution and compliance.

MN1381-J Applications

The MN1381-J is ideal for applications requiring precise voltage monitoring and reliable reset functionality. Some specific use cases include:

• Embedded Systems: In embedded systems where power supply integrity is critical, the MN1381-J ensures that the system remains stable and operates within safe voltage levels.
• Industrial Control Systems: For industrial applications where power fluctuations can lead to system failures, the MN1381-J provides a robust solution for monitoring and resetting power supplies.
• Telecommunications Equipment: In telecom systems, where uptime and reliability are paramount, the MN1381-J helps maintain system stability by monitoring power supply voltages and initiating resets when necessary.
• Legacy Systems: For older systems that still rely on through-hole components, the MN1381-J offers a reliable and compatible solution for power monitoring and reset functions.

Conclusion of MN1381-J
