NCP5214MNR2G is a special purpose voltage regulator designed by ON Semiconductor. It helps to maintain the operational voltage of the electronic device constant while providing effective power supply. It is used in a variety of applications in industrial, consumer, automotive and communication products. The device consists of two main components: a controller and a switching FET. It helps to control the output voltage in a range from 0.4V to 6V.

Application field

The NCP5214MNR2G is mainly used in automotive applications, such as automotive body systems, audio systems and infotainment. By using this voltage regulator, it is possible to ensure the stable power supply and increase the battery life. In addition, it can be used for power management in various industrial machine control and automation, renewable energy and medical devices.

The device is also a popular choice for consumer applications due to its compact size. It is widely used in different communication Components, such as cellphone, digital television and wireless devices.

Working Principle

The NCP5214MNR2G works by using a combination of linear regulation and switching regulation. The output voltage is kept constant using the combination of an internal voltage reference, error amplifier and error. The integrated voltage reference provides reference voltage that is compared to feedback voltage from the output of the programmable output divider circuit. If the output voltage is lower than the reference voltage, then the error amplifier will compensate by increasing the output voltage. Similarly, if the output voltage is higher than the reference voltage, then the error amplifier will compensate by decreasing the output voltage.

The micro SMT load switch is used to switch between two desired levels. The load switch can be programmed to two specific voltage levels in order to regulate the supply voltage. For example, if a device needs 3V supply, the load switch will switch between 3V and 6V, thus providing 3V supply to the device.

The device is also integrated with thermal shutdown and over-current protection features. The thermal shutdown feature will shut down the device when the internal temperature exceeds the junction temperature. The over-current protection feature protects the device from excessive current flow and helps to increase the product reliability.

In summary, the NCP5214MNR2G is a special purpose voltage regulator with wide range of applications. It is suitable for automotive, industrial, consumer and communication products, providing stable power supply and increased battery life. The device works by using linear and switching regulation. The integrated features such as thermal shutdown and current protection further improves the reliability of the product.
