FDY3000NZ Application Field and Working Principle

Introduction

FDY3000NZ is a type of power MOS Field Effect Transistors (FETs) array manufactured by the Fairchild Semiconductor Corporation. This type of FETs array is made up of two FDY3000NZ FETs, each individually paired with a resistor network. It offers excellent power performance and exceptional ease of application, thus helping to save board space and reduce production costs. Additionally, the device integrates a standard CMOS logic interface, making it suitable for digital and logic circuit applications.

Application Fields

FDY3000NZ is mostly used in power management applications including DC-DC converters, current control and power controller designs. Similarly, it is also suitable for power amplifier and motor drive applications.The FDY3000NZ offers efficient performance in high-speed switching and light-load applications. It is capable of delivering a very high output current of doubling the rated output current at its 5V supply, and a 20V isolation voltage is also provided. Furthermore, since the device is constructed using FETs and does not contain any mechanical parts, its switching action is highly reliable.The FDY3000NZ is also used in applications like motor drives, local loop telemetry and ancillary circuits, DC to AC inverters, bipolar switch mode power supplies, power conditioning systems, power delay networks and uninterruptible power supplies.

Working Principles

The FDY3000NZ is a voltage controlled FETs array, meaning that the device requires a voltage signal to control its operation. The drain current of the device is varied in proportion to the applied signal voltage.When the voltage signal is at its maximum, the drains of both FETs in the device are off, thus allowing full current to flow into the device’s output. Conversely, the minimum signal will switch the drains on, thereby reducing the current flow and effectively turning the FETs array into an open circuit.The device has a nominal gate voltage of 4.5V when control is off and a minimum gate voltage of 4V to power up the device. It operates with a maximum gate voltage of 6V, which is necessary for complete cutoff of the FETs.

Conclusion

The FDY3000NZ is an ideal choice for power management applications due to its ability to efficiently deliver high output current. It offers a cost effective solution since it eliminates the need for an external voltage output resistor network. Furthermore, it provides reliable switching action since it is constructed using FETs and does not contain mechanical parts. As such, this makes the FDY3000NZ suitable for a large variety of applications, ranging from DC-DC converters and current control to motor drive and power conditioning systems.
