PMIC supervisors are usually used in embedded boards, often as system reset functions, to reset the microcontroller every time the board restarts in order to ensure that the microcontroller is in its expected starting state. The XC6122C227MG-G is one such supervisor, which is one of the more popular ones due to its robust reset timing capabilities and its small size. In this article, we will discuss its application field, as well as its working principle.

The XC6122C227MG-G is mainly used as a reset supervisor for circuit designs, due to its high reliability, low power consumption, and excellent voltage supervisor accuracy. It is suitable for use in a wide range of applications, such as consumer electronics, automotive, home appliances, medical equipment and even life-critical applications such as space exploration and military electronics systems. The XC6122C227MG-G is used in many circuits due to its small size which allows for tight layout and cost-effective design. It also boasts a wide operating voltage range from 1.65V to 5.0V and minimum operating current of 1.5uA.

In terms of functionality, the XC6122C227MG-G can monitor power-on reset, as well as communication reset, and of course regular reset signals. With its watchdog timer functions, it can generate reset signals corresponding to power-on reset (POR) or soft reset (SR) along with a reset timeout. Its reset clearing delay (RCD) and reset asserting delay (RAD) parameters also ensure that the reset signal is sent out and received rapidly, thus providing a robust reset system.

The XC6122C227MG-G is also able to hold off reset signals until the proper power supply level is reached due to its push-pull open drain output. Furthermore, the delay time of the push-pull output can be adjusted through external capacitors, allowing the circuit to be optimized according to its respective power supply condition. Lastly, its shutdown timer provides an adjustable internal timer that will reset the circuit if it cannot be restarted within the preset time period. This is especially useful for applications that require a certain amount of time to boot up.

In conclusion, the XC6122C227MG-G PMIC supervisor is a highly versatile and reliable reset supervisor that can be used in a wide range of applications due to its robust power-on reset, communications reset, watchdog timer functions, and shutdown timer features. Its small size also allows for efficient circuit layout and cost-effective design, making it a popular choice for designers who need a reliable reset supervisor.
