Allegro Driver Recommended by GaN Systems in Bodo's Power System December Issue
The AHV85110 (Hey1011) gate driver is recommended as the 1st step to achieve highly-effective GaN designs.
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).
