Whether you’re an engineer looking for the best gate driver for your project or a tech fan who wants to know what it can do, this guide will give you useful information.

IX4427NTR Overview

Dual Non-Inverting Gate Driver for Driving Power Devices

The IX4427NTR is part of a special family of dual high-speed, low-side gate drivers made to meet the needs of high-frequency and high-power uses. Along with the IX4426 and IX4428, this gate driver has great performance and can be used in many different types of power electronics systems.

Part of a Gate Driver Family

The IX4427NTR is a member of a well-known family of gate drivers made by top semiconductor companies. The IX4426, IX4427, and IX4428 are all in this family. Each one is made for a different configuration and purpose. While the IX4426 is a dual inverting driver and the IX4428 is a combination of one inverted and one non-inverting drivers, the IX4427 stands out as a dual non-inverting gate driver. Because of how it is set up, both of its outputs can give the same information about the input. This makes it an important part of power electronics circuits.

Significance in Driving Power Devices

As a dual non-inverting gate driver, the IX4427NTR is a key part of driving power devices like MOSFETs and IGBTs. Many high-power uses, like motor drives, switch-mode power supplies (SMPS), class D audio amplifiers, renewable energy systems, and high-frequency converters, use these power devices.

Advantages of Non-Inverting Configuration

The IX4427NTR’s non-inverting design has the following benefits in power electronics applications:

  • Signal Integrity: By guaranteeing that both outputs produce the same signals as the input, power device switching is accurate and synchronized.
  • Phase compatibility: The non-inverting properties enable seamless system integration without generating phase changes or timing inconsistencies.
  • Enhanced Efficiency: The gate driver decreases switching losses and improves system efficiency overall with low signal distortion and high-speed performance.

Non-inverting gate drivers are preferred for motor drive applications because they provide precise and effective motor control.

Key Features of the IX4427NTR: Enhancing Performance and Reliability

A potent twin high-speed, low-side gate driver with excellent performance in high-frequency and high-power applications is the IX4427NTR. Its fundamental characteristics make it a top choice for driving power devices in a variety of systems due to its remarkable performance and dependability.

Dual Outputs

The presence of two outputs in the IX4427NTR offers several advantages:

● Parallel Drive Capability

The parallel drive capability of the dual outputs provides efficient and balanced functioning of the power electronics system by enabling simultaneous and synchronized control of two power devices, such as MOSFETs or IGBTs.

● Dead-Time Control

By employing both outputs, designers may regulate dead time, eliminate shoot-through currents, and reduce switching transition power losses.

● Phase Synchronization

The twin outputs in multi-phase applications allow for precise phase synchronization, which is necessary for high-efficiency power conversion and motor control.

High-Speed Performance

The importance of fast switching times in the IX4427NTR cannot be overstated:

● Reduced Switching Losses

When switching between the on and off states of the power devices, switching losses are minimized by the gate driver’s quick rise and fall periods, which are typically less than 10ns. This improvement in efficiency leads to better system performance overall and less power loss.

● High-Frequency Operation

High-frequency applications benefit from the IX4427NTR’s high-speed capability because it enables power converters and motor drives to run at higher frequencies, resulting in smaller, lighter, and more effective designs.

● Peak Current Handling

Peak current handling capacity of the IX4427NTR is a critical attribute for demanding applications:

● Robustness and Reliability

The gate driver is capable of driving high-power MOSFETs and IGBTs because each output can source and sink 1.5A of peak current. For applications with variable load demands, its robustness guarantees reliable operation even under high-current and high-voltage circumstances.

Overcurrent Protection

The peak current handling capacity helps the system’s built-in overcurrent protection prevent harm from large currents, protecting the system’s power devices.

● TTL and CMOS Compatibility

The IX4427NTR gives a lot of flexibility because it is compatible with TTL and CMOS logic signals:

● Wide Range of Control Circuits

The gate driver makes system integration and design simpler by smoothly integrating with a variety of control circuits that use TTL or CMOS logic levels.

● Easy Interfacing

Without the need for level-shifting circuits, engineers may quickly link the gate driver to microcontrollers, digital signal processors (DSPs), or other logic devices, expediting the whole design process.

Latch-Up Immunity

The benefits of latch-up immunity make the IX4427NTR highly reliable and durable:

● Protection Against Latch-Up

In semiconductor devices, latch-up is a possible failure mode where a low-impedance route develops between the power supply rails. The IX4427NTR is essentially immune to this problem thanks to its architecture, which also protects against latch-up and increases system reliability.

● Stable and Safe Operation

Particularly in difficult circumstances or when exposed to fleeting occurrences, the latch-up immunity assures reliable and secure functioning.

Its remarkable performance, dependability, and flexibility in high-frequency and high-power applications are largely due to the IX4427NTR’s essential features, including latch-up immunity, dual outputs, high-speed performance, peak current handling, TTL and CMOS compatibility, and high-speed performance. These characteristics can be used by engineers and designers to build reliable, high-performance power electronics systems for a variety of industrial and automotive applications.


The IX4427NTR is a powerful and efficient dual high-speed, low-side gate driver that caters to a wide range of high-frequency and high-power applications. Its fast switching times, peak current handling, and compatibility with various logic levels make it a reliable choice for driving MOSFETs and IGBTs in different systems. Whether you are working on power electronics, motor control, audio amplifiers, or renewable energy systems, the IX4427NTR can significantly enhance the performance and efficiency of your design.
