XC6120N122NR-G is a low drop-out, high performance, single output voltage regulator dedicated for applications requiring high precision in ultra-low current consumption. It is designed with advanced features and grade of high stability to protect system from abnormal power supply condition and prevent Data corruption. Ideal for applications in wide operating range from 0.9V to 5.5V, XC6120N122NR-G brings reliability and easy operation to an integrated solution in all kinds of applications.

XC6120N122NR-G is categorised as a PMIC (Power Management IC) Supervisors, which are hardware components that detect or monitor various conditions or aspects of the power supply design, such as overvoltage, undervoltage, and current flow. PMIC Supervisors are used to prevent devices or components in a system from incurring damage due to changes in voltage level, excessive current imput, or other harmful conditions and alerts the user through integrated signals or external interrupts. This integrated power management IC, XC6120N122NR-G, is an ideal choice for achieving high precision voltage regulation and power saving in many applications due to its dual main supply and low RDS(ON) junction.

Working Principle

XC6120N122NR-G works by incorporating a high current N-MOSFET switch between the input and output stages. The low-side switch operates on a single voltage supply, allowing for higher efficiency and simpler control interface. An integrated voltage reference allows for high regulation accuracy, tightly controlling the output voltage of the device. It also features an enable pin, so the n-MOSFET can be switched on and off by controlling this pin. The power-on-reset pin is used to detect if the system is powered on, so the device can automatically detect its operating state and begin regulating the output voltage. It also includes an under voltage lockout (UVLO) circuit which detects low voltage conditions, and when triggered, prevents the device from entering the switch mode.

The control of the n-MOSFET switch is achieved by a Pulse Width Modulation (PWM) control mechanism. This method is used to pulse the voltage rail in a sequence, which then determines the average voltage at the output. The high switching frequency allows for better regulation accuracy, which is one of the main advantages of using this type of PWM control. The integrated current monitoring block is further used to provide protection against over-current conditions, whilst the thermal protection circuit limits the peak junction temperature. The comprehensive protection mechanisms make XC6120N122NR-G an ideal choice for many applications demanding high precision voltage control and power saving.

Applications

XC6120N122NR-G can be used in a wide range of applications that demands high precision voltage regulation and low quiescent current. Max input voltage range of 5.5V can be used to power microcontrollers and other commonly used devices used in automation and controlling systems. Also, it can be used in small-volume battery powered equipment, where high power efficiency is crucial. It can also be used in low-power systems, such as energy meters, healthcare devices and home appliances due to its wide operating range and low quiescent current.

XC6120N122NR-G is also suitable for applications that require over-voltage and under-voltage lockout features, such as industrial control systems and automotive applications, as well as mobile communications. Furthermore, it can be utilized in different applications which require the application of multiple voltage levels, as it provides high precision voltage control in different output stage.
