NCP5378MNR2G

NCP5378MNR2G application field and working principle

NCP5378MNR2G belongs to a product series of Power Management Integrated Circuits (PMICs) offered by an industry leading semiconductor company, ON Semiconductor. This integrated circuit is within the product classification of PMIC – Voltage Regulators – Special Purpose. It functions as a power supply voltage monitor and voltage regulator which is designed for automotive applications.

NCP5378MNR2G is uniquely designed to withstand harsh automotive temperature conditions (junction temperature range of -40°C to 130°C). It has a low shutdown current of 1.5µA at +25°C, and an advanced logic-controlled under-voltage lockout. This integrated circuit is also characterized with a high precision enable / disable function and a wide operating voltage range (8V to 36V) which seamlessly meets the requirements of 12/24V automotive systems.

Working Principle of NCP5378MNR2G

NCP5378MNR2G works on the principle of linear regulation. This integrated circuit is essentially a voltage regulator which acts as a voltage monitor and supplies regulated voltage & current to various automotive electronic components. It does this by measuring the voltage of a source and adjusting the output accordingly. If the source is at a higher voltage, the output voltage is adjusted such that the output is still a lower voltage than the input. On the other hand, if the input voltage is lower, the output is kept at the desired value. In either case, the NCP5378MNR2G ensures that the output voltage remains in the range of its operating specification range, which is 8V to 36V. The precision of this regulation depends on the accuracy of the integrated circuit\'s monitoring circuitry.

The integrated circuit\'s monitoring circuitry can itself be adjusted for either long or short loop duration depending on the application. In either case, the monitoring circuitry ensures that the output voltage stays within the operating specification range. The integrated circuit is also equipped with current limiting feature which prevents over-current conditions from occurring which may damage the device or the connected components.

Applications of NCP5378MNR2G

NCP5378MNR2G is mainly used as a voltage regulator and monitor in automotive applications. It can be used to control power systems in a wide range of vehicles ranging from cars, buses, and trucks to even off-road vehicles. It is also suitable for automotive applications requiring a wide input voltage range (8V to 36V) and tight output voltage control over temperatures ranging from -40°C to 130°C.

Some of the applications of NCP5378MNR2G include powering motor drive electronics, protection against over-voltage / under-voltage events, and reliability improvement in electronic control units (ECUs). It can also be used for a wide range of automotive applications such as automotive controllers, safety systems, HVAC systems, and engine management.
