FAN7390MX Introduction

Are you looking for a high-performance gate-drive integrated circuit capable of managing high-speed MOSFETs and IGBTs with a maximum operating voltage of up to +600V? There is no need to go any farther than ON Semiconductor’s FAN7390. This monolithic high- and low-side gate-drive IC features a buffered output stage comprised entirely of NMOS transistors. It was developed with the capacity to drive high pulse currents and with the least amount of cross-conduction possible.

Furthermore, ON Semiconductor employs a high-voltage process and common-mode noise reduction methods; you can believe that the FAN7390 will guarantee steady performance of the high-side driver even when subjected to conditions with a high dv/dt noise level. Because of its sophisticated level shift circuit, it is possible to operate the high-side gate driver up to VS = -9.8V (typically) for VBS = 15V. The FAN7390 is an excellent option for a wide range of applications thanks to its UVLO circuit, which prevents malfunctions, as well as its high current and low output voltage drop features. Some examples of these applications include PDP sustain pulse drivers, switching power supplies, motor drivers, and high-power DC-DC converters.

FAN7390MX Description

It is possible to operate high-speed MOSFETs and IGBTs with the FAN7390 since it is a single-chip solution for both high- and low-side gate driving. Its operating voltage range is up to +600 V. It possesses a buffered output stage constructed entirely out of NMOS transistors and designed for strong capability to drive pulse current with low cross-conduction. Under high dv/dt noise conditions, the high-side driver from ON Semiconductor can maintain steady operation because of the company’s high-voltage method and ability to block out common-mode noise.

An innovative level shift circuit allows high-side gate driver functioning up to VS = 9.8 V (typical) for VBS = 15 V. The voltage range is specified in volt-seconds. When VBS and VDD are lower than the specified threshold voltage, the UVLO circuit prevents any problem from occurring. This component is ideal for use in the PDP sustain pulse driver, switching power supply, motor driver, and high-power DC-DC converter applications thanks to its high current output and low output voltage drop characteristics.

Gate Drivers Half Bridge Gate 600V .625W

Gate drivers are necessary components in power electronics; they play an important part in the process of driving and controlling power switches such as MOSFETs and IGBTs. Gate drivers can be found in both discrete and integrated form. The fundamentals of Half Bridge Gate Drivers for 600V applications with a power rating of 0.625W will be covered in depth throughout this tutorial.

One variety of gate driver circuit is known as a Half Bridge Gate Driver. This driver circuit powers two switches, often MOSFETs or IGBTs, coupled in a half-bridge arrangement. The half-bridge configuration allows current to flow in both directions and allows the circuit’s output voltage to be controlled.

While shopping for a Half Bridge Gate Driver, the maximum voltage rating is one of the essential characteristics to consider. In this particular scenario, we are searching for a driver capable of working with voltages of up to 600V. In addition to this, it is extremely important to consider the driver’s power rating, which is normally expressed in watts. A power rating of 0.625W is considered relatively low and may be appropriate for applications requiring low power.

The output current capability of the Half Bridge Gate Driver is another important parameter that must be taken into consideration. According to this standard, the driver can supply a maximum amount of current to the gate of the switches. To ensure that the switches can turn on and off in a timely manner, it is required to have a high output current capability.

In addition to being an essential need, the switching speed of the Half Bridge Gate Driver is also very important. This criterion, measured in nanoseconds, establishes how rapidly the driver can turn the power switches on and off. In most cases, a faster switching speed is desired because it reduces switching losses.

While choosing a Half Bridge Gate Driver, it is also necessary to think about the device’s thermal management, as well as its protective features and its size. It is imperative to have effective thermal management in place to guarantee that the driver will function within the allotted temperature range. Protective elements that help avoid damage to the driver and the switches include overcurrent protection, overvoltage protection, and undervoltage protection. The size of the driver is also quite important because it might affect the total size and weight of the product once it is finished.

Half Bridge Gate Drivers are, all things considered, a key component in power electronics; hence, it is imperative that you choose the appropriate driver for your particular application. It is essential to consider the maximum voltage rating, power rating, output current capability, switching speed, thermal management, protection features, and driver size when selecting one for an application that requires a power rating of 0.625W and has a voltage rating of 600V. By considering these specifications, you can ensure that you select the right Half Bridge Gate Driver for your application.


In summary, the FAN7390MX is an excellent choice for driving high-speed MOSFETs and IGBTs, with its high-performance and protective features. Half Bridge Gate Drivers are crucial components in power electronics, and choosing the right one requires careful consideration of various factors.
