Power Management IC (PMIC) supervisors are essential for reading, interpreting and conditioning voltage levels for a wide range of electronic products. The CAT812MTBI-GT3 is a PMIC supervisor from ON Semiconductor that is designed to provide rail monitoring and functionality control to modern systems. It offers voltages ranging from 0.56V to 2.6V, internal MOS source and sinking capability, and multiple trip points for monitoring and control. This article will discuss the importance and applications fields of the CAT812MTBI-GT3 and its working principle.

Applications

This supervisor can be found in a number of embedded systems, for example consumer electronics, digital home appliances, smart meters, and industrial sensors. The CAT812MTBI-GT3 combines its integrated voltage-scalable comparators, precision reference voltage and an output transistor-based driver. This allows system designers to add rail monitoring and smart outputs without any external components. This supervisor is offered in a small 3mm×2mm MLP package providing a reliable, cost-effective solution for applications where space is a critical factor.

The device also offers several features that are beneficial for embedded system designers, such as low-power consumption, high accuracy, temperature monitoring, and multiple trip points. With the added features and small size, the CAT812MTBI-GT3 is an excellent choice for a variety of applications.

Working Principle

At the heart of the CAT812MTBI-GT3 lies its integrated voltage-scalable comparators, precision reference voltage and an output transistor-based driver. This allows the supervisor to read the voltage of the system it is being used in, interpret it and then condition the voltage, ensuring it is within the required range.

The CAT812MTBI-GT3 offers six trip points, three for monitoring and three for controlling the output. The three monitoring trip points are low voltage monitor, high voltage monitor, and input threshold monitor. These allow the supervisor to monitor different parts of the voltage and output a warning before any problems can occur. The three controlling trip points are voltage raise, voltage drop and high voltage lockout. These allow the supervisor to adjust the output when needed to ensure the voltage is within the required range.

The CAT812MTBI-GT3 also has an integrated temperature sensor which can be used to monitor the temperature of the system. The temperature monitoring feature is useful for applications that are subjected to extreme temperatures as it can prevent unwanted problems that could occur due to inefficient cooling.

Conclusion

The CAT812MTBI-GT3 is a Power Management IC (PMIC) supervisor from ON Semiconductor. It is designed to provide rail monitoring and functionality control to modern systems and is especially useful for applications that have very tight space constraints. The supervisor offers multiple trip points, a temperature sensor and an output transistor-based driver which allows it to read, interpret and condition voltages accurately and effectively.
