IX4340NETR Application Field and Working Principle

IX4340NETR is a high-performance, level-shifting, segmented I/O gate driver from IXYS Corporation, classified as a PMIC - Gate Drivers. This gate driver can function as a non-isolated, three-phase intelligent site driving power supply IP (intellectual property) core chip. It is widely used in a variety of applications, from home appliances to industrial control systems.

Base Functionality

IX4340NETR provides a cost-effective and efficient solution for driving six-phase inverter circuits. It is exclusively designed for powering load integrated circuits, such as three-phase BLDC/PMSM and two-phase BLDC/PMSM. Its optimized base platform offers reliable, flexible, and easy to use power delivery systems.

In addition, the IX4340NETR chip offers dynamic PWM performance, allowing the user to program and control the drive parameters of their inverter or power converter design with just a few programming registers. The in-built logic auto-detect functionality in IX4340NETR further ensures that the correct power supply pinouts are provided to the system – maximising reliability and performance.

Advantages

This gate driver provides both accuracy and cost-efficiencies by eliminating the need for external driver circuitry. Moreover, its integrated three-phase bridge drive provides motor control with a high level of flexibility, allowing designers to use it in applications that require high precision, such as robotics.

The IX4340NETR also offers a range of safety and performance-enhancing features. Its built-in over-temperature protection prevents your device from over-heating and protects components and circuitry from being damaged.

Moreover, the IX4340NETR features power loss protection, which prevents the system from dropping into protection-wrecking sleep modes when power is cut off. Additionally, it is capable of low-voltage monitoring and provides a full-featured energy feedback loop to ensure that your system is running at its optimal levels.

Working Principle

The working principle of the IX4340NETR is that it receives input voltage from a power supply and transmits it to the system. This is made possible by the chip\'s gate drive architecture that combines level shifting and segmented I/O control. In this architecture, three separate power stages are connected in series with each other, which are the input port stage, the level-shift port stage and the output port stage.

The voltage output at the output port is determined by the level shifting performed in the level-shift port. For this purpose, the name IX4340NETR is derived: “I” stands for “Input” and “X” stands for “Level Shift”. The output port also serves to rectify the signal, which is then sent to the system from the output port.

Conclusion

The IX4340NETR gate driver provides a high-performance driving power for three-phase and two-phase BLDC/PMSM circuits. Its base platform is optimized for cost-effective and efficient solutions for driving power inverters, providing a great deal of reliability and flexibility for emerging applications. Moreover, the in-built features of this chip, like over-temperature protection, low-voltage monitoring, and energy-feedback loop, ensure effective performance and safety.
