PMIC - Supervisors are a type of integrated circuit which can be used to monitor, control, and protect electronic devices. The XC6122C747MR-G is a CMOS Supervisory Circuit which can be used to provide over-voltage protection and power good reset signals. It is a low power and low cost supervisor which is suitable for a wide range of applications.

Application Field:

The XC6122C747MR-G has a wide range of applications, such as power supplies, audio amplifiers, opto-electronic displays and computer peripherals, as well as other consumer electronics. It is primarily used for controlling the power-on and power-off of a device. It is also used to detect over-voltage, under-voltage, or over-temperature conditions.

Working Principle:

The XC6122C747MR-G consists of three main sections. first, the power supply is monitored by the over-voltage, under-voltage and over-temperature monitors. The input voltage can be monitored to ensure it is within a safe range. If the voltage is outside of a specified range, the reset signal will be activated to prevent the device from damage. The second section is a watchdog timer which monitors the microcontroller to ensure it is running properly. If an overload or fault occurs, the reset signal will be activated to reset the microcontroller. The third section is the power good monitor which ensures that the power supply has stabilized.

The XC6122C747MR-G can be powered by a 5V supply, requires a minimal number of external components, and features a power-on reset with a reset output active low. It has a wide range of operating temperatures from -40°C to 85°C, and is available in a SOIC-8 package. The output phase can be manually adjusted via the programming pin which allows the output to be turned off or on.

Overall, the XC6122C747MR-G is a low power CMOS Supervisory Circuit which is suitable for a wide range of applications. It is able to provide over-voltage protection and power-on reset signals and requires minimal external components for installation. It is also available in a range of operating temperatures, making it suitable for various environments.
