Isolators - Gate Drivers have a wide variety of applications in the field of power electronics and signal transmission. In this article we will discuss one such application, IX3120GSTR, and its working principles.

IX3120GSTR integrates two 7.5 MW transistors for driving high-side and low-side MOSFETs. It operates similarly to a universal gate driver, allowing the user to select from several common and standard logic families depending on their specific power requirements. This Isolator-Gate Driver is applicable to many gate drive applications, such as motor drives, power inverters, industrial control systems, power conditioners, and LED lighting.

The IX3120GSTR isolates gate drive signals so that the vISH and vLSH pins of the dual MOSFETs are driven independently. This provides better control of the switching signals and improved noise immunity. The driver features a thermal shutdown circuit to protect the device from over-temperature and fast current limiting to protect power gate drivers against load surges.

The working principle of IX3120GSTR is fairly straightforward. A controller such as a microprocessor sends a signal to the gate driver, which then uses it to activate the MOSFETs. The gate driver converts the logic signals to appropriate voltage levels, which are then connected to the isolator\'s isolated output. The Isolator then feeds the switched voltage or current to the gate terminals of the MOSFETs, activating them. This switching process is often used to control the speed or torque of a motor, or for AC or DC power conversion.

The IX3120GSTR also features an improved ripple rejection capability compared to other drivers, providing up to 50dB of ripple rejection. This allows for improved communication between the two power devices and significantly reduces electromagnetic interference. This Isolator-Gate Driver also features built-in ESD protection and wide temperature range operation, with a temperature range from -40°C to 85°C.

In summary, IX3120GSTR is a versatile Isolator-Gate Driver that can be used in a variety of applications. It features advanced protection measures such as current limiting and thermal shutdown, as well as improved ripple rejection and ESD protection. This makes the IX3120GSTR an ideal choice for applications that require isolation and reliable gate drive control.
