PMIC - Supervisors
To understand what a XC6122C232MG-G is and its application field, one must first understand the basics of a PMIC (Power Management Integrated Circuit). A PMIC is an electronic circuit module, usually dedicated to managing the power of a system. It consists of multiple built-in voltage regulators, current limiters and other components, allowing for fast, accurate and efficient regulation of system power. The XC6122C232MG-G is a type of PMIC, specifically a supervisor, designed for microcontroller-based systems.
The main aim of a supervisor is to provide protection against out-of-range input voltages and over/under-current conditions. Using dedicated hardware, the supervisor will detect when the voltage of an input signal goes out of range and either disable the power supply or apply a reset signal. It also provides a number of configurable shutdown or reset signals to microcontrollers in the event of under or overvoltage and over current faults.
The XC6122C232MG-G is a three-pin supervisor with active-low fault (reset) output and two active-high power-supply monitoring outputs. The device operates with a supply voltage between 2.4V and 5.5V and provides OV/UV/OVL monitoring and timer reset functions. It features an integrated circuit temperature sensor and a watchdog timer, providing an adjustable timeout period from 1ms to 2000s. It also has high-accuracy comparator input limits for high precision monitoring.
The XC6122C232MG-G has several application fields. It is mainly used in microcontroller-based systems, such as microprocessor systems, embedded systems, and embedded microcontroller systems. It is also often used in low-power sensors, as it provides protection against under or overvoltage conditions. Additionally, it is suitable for use in automotive applications, where it can provide protection against overcharging, input voltage spikes, and overcurrent conditions.
Working Principle:
In order to ensure a system’s power supply stays within an acceptable range, the XC6122C232MG-G monitors the input power supply voltage and any other externally supplied signals. It uses comparator input limits to detect when the voltage goes above/below a given level. When this happens, it either disables the power supply or activates a reset signal.
In addition, the watchdog timer function monitors digital signals coming from the microcontroller to make sure it is running properly. If the microcontroller does not send a predetermined number of signals within the specified period of time, the supervisor will detect this and activate the reset signal.
Conclusion:
The XC6122C232MG-G is a three-pin PMIC supervisor designed for microcontroller-based systems. It provides protection against out-of-range input voltages, over/under-current conditions, and input voltage spikes, as well as a watchdog timer to make sure the microcontroller is running properly. It is mainly used in microcontroller-based systems, low-power sensors, and automotive applications.
