Today, we are going to discuss the application field and working principle of XC6121F731MR-G, a product from Supervisors that falls into the family of PMIC (power management IC).XC6121F731MR-G is a low voltage supervisor specially designed for the systems which need to monitor the system\'s working voltage at low level. It provides a reset signal to the system when the working voltage is not in the operating range. In addition, its operating temperature provides more convenience to its application field.

When talking about the application field of XC6121F731MR-G, as mentioned before, it can be used in a low voltage environment such as the system of industrial instrument or control, etc. In addition, it can be applied to the communication control system in order to supervise the power supply and keep system running. Furthermore, it also supports 0.3V (typical) while consuming low current.

In addition to the application field, let\'s focus on the working principle of XC6121F731MR-G.

The working principle of XC6121F731MR-G is quite simple. It senses the voltage of the power supply and compares it with the preset reference voltage so as to reset the system when the working voltage is out of the pre-determined range.

Besides, unlike other low voltage supervisor, XC6121F731MR-G features an Activation Delay function. This feature allows the system to wait until the activation delay times out and resets the system if it is not in the acceptable voltage range. This feature is quite helpful when the system experiences an aberrant start up or when the power supply voltage is too low to be regarded as in the correct operating range.

To verify its monitoring capability, the open collector output can be utilized to generate the reset signal which can be observed with a digital tester. Moreover, XC6121F731MR-G also features a Delay Cancel function that enables the system to restart running as soon as the power supply voltage is near the working voltage even when the system has experienced many aberrant start-ups.

In short, the application field of XC6121F731MR-G is low voltage environment such as the system of industrial instrument or control and communication control system, its working principle is to sense the voltage of the power supply and compare it with the preset reference voltage so as to reset the system when the working voltage is out of the pre-determined range and it features an Activation Delay and Delay Cancel functions. With these features, XC6121F731MR-G is surely a great choice for low voltage systems and communications.
