Isolated Gate Drivers

Fully integrated isolated gate drivers for GaN, MOS, and SiC

GaN and SiC power devices are gaining market share rapidly in electric vehicle and industrial applications, such as renewable energy and datacenters.

Allegro Power-Thru technology significantly reduces system design time and complexity and makes it possible for designers to take advantage of the full efficiency benefits that WBG switches provide thanks to its isolated gate driver solutions. They use a single, small-footprint package that integrates an isolated gate driver, an isolated power supply, and associated passive components.

The Power of Simplicity

Our self-powered devices provide high-speed gate driver & isolated supply all in one package.

  • Say goodbye to bootstrap components
  • Remove bulky DC-DC isolated power modules
  • Significantly reduce EMI noise and common mode capacitance
  • Achieve higher efficiency and higher power-density than with any other solution
  • Simply enable the higher performance of multilevel topologies, by removing most complexity

Creating Superior Modules

Achieve Low Common Mode Capacitance

Typically 10 to 15x smaller than competition

Increase Power Density

Typically 15 to 50% more power in the same volume

Reduce Component Count

Typically 20 to 50% less BOM count

Create the Most Simple and Integrated Solution

With up to 40% less different components per system compared to a solution with GaNFET with integrated driver

Reduced Bias Power Consumption

Typically save 50 to 65% and up to 1.5W per half-bridge

Unlock the Advantages of Multilevel Topologies

Removing the need for multiple isolated power rails make your multilevel design feel nearly as easy as child's play. Allegro's Power-Thru technology let you achieve ultra-high power-density and efficiency at lower cost without the complexity.

Unique Gate Driver Benefits

No need for an isolated supply

With Allegro's isolated driver you don't need a separate isolated supply.  This means lower BOM count, less PCB area and improves the robustness and EMI performance of your converter.

Short propagation time

Both the ON and OFF propagation times are very short (25ns typ).  This makes dead-time management between switch cycles easy to manage and helps to maximize the efficiency of the power converter.

Continuous ON time capability

Would you like to drive your switch ON or OFF for a long time without having to worry about recycling energy into a bootstrap capacitor?  With the Allegro isolated drivers that's taken care of for you.  Infinite ON and OFF time capability comes as standard.

Separate pull-up/pull-down pins

This enables the system designer to freely choose a resistor value for turn ON (pull-up) and turn OFF (pull-down).
