Introduction

STM6315RAW13F is a device categorized as Power Management Integrated Circuit (PMIC), also known as Supervisors. It has a wide range of applications and its working principle is designed to help improve and protect other devices that are powered by the main power source.

Overview of STM6315RAW13F

The STM6315RAW13F is programmable to provide one voltage reference of 1.2V and one of 1.8V. It also has a power monitoring comparator, two primary supervisor and two complementary supervisor inputs, and two reset outputs. The primary supervisors are designed to activate when the supply voltage is below a programmed threshold. The complementary supervisors activate when the supply voltage is above a different programmed threshold.

Application Field

The application field of STM6315RAW13F is broad and highly versatile. Its primary application is as a supervisor in a variety of systems requiring voltage regulation. The device is commonly used in embedded control systems to detect and control power changes, and is highly reliable for device resetting and voltage monitoring. The STM6315RAW13F is ideal for use in motor control systems, medical/life support equipment, automotive equipment, as well as in high-efficiency switches, processes, high-speed automation machines, etc. Therefore, the device can easily provide optimized power supply to the given device.

Working Principle

The STM6315RAW13F works according to an under voltage voltage sensing principle. This is when the output voltage falls below a predetermined threshold level, which causes the reset output to output a low signal. In this state, all the devices in the system are reset, forcing them to regain their natural or ‘normal’ operation. The STM6315RAW13F also works according to an overvoltage sensing principle. This is when the supply voltage exceeds a predetermined threshold, which causes the reset output to output a high signal. This indicates that the supply voltage is too high, and the false reset behaviors that may cause data loss or system malfunction can be eliminated.

Conclusion

In conclusion, the STM6315RAW13F is a PMIC - Supervisors with a wide range of application fields and an effective working principle. The device is designed to detect and control power changes, and is used extensively in embedded control systems to detect the supply voltage and reset other devices during disturbances in supply voltage. The STM6315RAW13F is employed in multiple fields ranging from automotive to medical devices and it has proved to be highly reliable in providing power supply to the given device.
