Gate driving : simple & powerful

With unique power-thru technology  : 
  • no more isolated supplies
  • no more bootstrap components
Resulting in excellent performance levels 
Designing a new module has never been as simple and as fast 

Unique Gate drive benefits

  • No need for an isolated supply

    Typically an isolated gate driver device requires a separate isolated supply.  This is either an off-the-shelf module or a custom isolated supply designed into the power converter.  With Heyday's isolated driver you don't need a separate isolated supply.  Our driver does that for you.  This means lower BOM count, less PCB area and improves the robustness and EMI performance of your converter.

  • Short propagation times

    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 Heyday 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).

Creating superior Modules

  • Reduce switching losses

    Lower propagation times = smaller dead times
  • Increase reliability

    • Less components means more reliability 
    • Robust design
  • Easier design for safety

    No need to design a custom isolated supply into your power converter.  It's already done for you with the Heyday drivers! 
  • Reduce your module weight

    Reduce your module weight by eliminating that custom isolated supply and all the components that entails: 

    • extra magnetic's
    • extra winding's 
    • extra silicon & passive components
    • separate isolated supply module

Leverage these gate drive benefits at module level

Create competitive advantage - faster


Heyday's unique benefits go far beyond the driving.

The whole module benefits from increased simplicity and efficiency.
