NCV47821PAAJGEVB devices are linear voltage regulators designed to provide high performance voltage regulation for applications in automotive and industrial equipment. The device can be configured for a wide range of input and output voltages and is capable of driving very high current loads up to 10A. The NCV47821PAAJGEVB is an integrated N-channel MOSFET, Operational Amplifier, voltage and current regulator, and a voltage comparator. This single integrated solution allows for the elimination of the discrete components traditionally used to build voltage regulators.

Application Field

The NCV47821PAAJGEVB is ideal for a variety of applications, including:

• Automotive systems, including fuel injection, airbags, seat belt pre-tensioners, and powertrain controls
• Industrial equipment, such as motor and compressor drives, HVAC systems, AC/DC converters, and power supplies

The NCV47821PAAJGEVB is designed for efficient power conversion in a wide variety of industrial and automotive applications, providing high performance, low power consumption, and low component count. The integrated MOSFET provides low RDS(ON), excellent thermal performance, and fast transient response, while the operational amplifier regulates the output voltage to maintain it within tight tolerance levels. The voltage and current regulators protect the device from current overloads and short circuits, and the voltage comparator automatically shuts down the MOSFET whenever an overvoltage condition is detected, protecting both the components and circuitry.

Working Principle

The NCV47821PAAJGEVB consists of four integrated components (MOSFET, OPAMP, Voltage Regulator, and Comparator), which each play an essential role in the device\'s operation. The MOSFET is responsible for converting the input voltage into the desired output voltage. The operational amplifier is used to ensure that the output voltage remains within a tight tolerance range. The voltage regulator limits the current draw and prevents overloading of the MOSFET, while the comparator monitors the output voltage and shuts down the MOSFET whenever an overvoltage condition is detected. These four components enable the NCV47821PAAJGEVB to deliver high performance, stable, and reliable voltage regulation.

In operation, the device works by first accepting an input voltage. The integrated MOSFET converts the input voltage to an appropriate output voltage based on the voltage feedback from the operational amplifier. The voltage and current regulation circuitry prevents current overloads and the comparator monitors for overvoltage conditions which could damage the MOSFET. When the output voltage exceeds the specified upper limit, the comparator triggers the MOSFET to shut off, preventing damage to the system.

The NCV47821PAAJGEVB offers numerous advantages in addition to its compact size and low power consumption. It has a wide input/output voltage range, high efficiency, and is capable of driving very high currents. It also has excellent thermal performance and is ESD protected.
