The MN13812-E is designed to help keep equipment running with optimal performance and reliability.

Application Field and Working Principle

The MN13812-E is a member of the PMIC (Power Management ICs) Supervisors family of products. It is designed to provide essential power and reset monitoring functions for embedded systems, communication systems, and other industry-standard applications. It is a universal solution that meets the monitoring needs of a wide range of embedded applications, significantly reducing the design and development time.The MN13812-E is specifically designed for monitoring power management implementers such as low-power microprocessors, gate arrays, system controllers, peripherals, and memory caches. It also serves as a watchdog timer, resetting the system when a timeout condition occurs after a configured period of time. Its small 1mm by 2.36mm HVSSOP package, which is the same as a 1mm x 2.5mm SOIC package, enables it to fit in compact designs.The MN13812-E offers convenient and configurable power management sequencing by providing several diverse reset options as well as sequencing and sequencing control options. It also features power management reset and power-down reset. The MN13812-E follows an effective working principle to ensure the reliability of the system, easily integrating with externally triggered manual reset, watchdog reset, and windowed watchdog reset. It monitors the power supplies for under-voltage or over-voltage condition. In addition, it tracks power supply status and issues indication signals in case of a power supply anomaly.

Conclusion

The MN13812-E offers a wide range of features, making it an ideal choice for embedded applications. It provides a universal solution that meets the monitoring needs of different applications and ensures the reliability of the system, providing essential reset monitoring functions. It is designed to fit in small designs, which makes it suitable for space-constrained applications. The wide range of reset options, along with its configurable power management sequencing, make it an ideal choice for any embedded system.
