Infineon’s New Gate Driver IC 1EDN offers Low Power Consumption and High Robustness


Infineon Technologies introduces the new 1EDN EiceDRIVER family which comes in a 1-channel low-side gate driver IC and is sought to be a perfect fit to drive MOSFETs, IGBTs as well as GaN power devices.

Its pin-out and packages are touted to be fully compatible to the industry standard which eases the drop-in replacement for existing designs.

Lower Internal Power Consumption 

Compared to other 1-channel low-side gate driver ICs, the 1EDN EiceDRIVER family from Infineon leads the industry in low internal power consumption. The low-ohmic output stages translate into a higher efficiency of more than 30 percent. This allows for additional design flexibility and driving more power devices whilst staying within the thermal budget.

The outputs of the 1EDN family feature an industry-leading reverse current robustness of 5 A. This eliminates the need for protection diodes when driving MOSFETs with large parasitic source inductances typically found in TO-220 or TO-247 packages. With the new driver ICs customers can thus save on both, BoM and PCB area.

The 1EDN portfolio excels by its -10 V input robustness securing a crucial safety margin against ground-shifts when driving gate-transformers. This extra noise robustness protects against electrical overstress of the inputs or latch-up of the driver IC. Additionally, the 1EDN family includes variants with separate source and sinks output terminals. This eases the turn-on and turn-off speed optimization, concurrently saving one external diode. The 1EDN EiceDRIVER family is in volume production and will be showcased at electronica 2016.

Applications include:

Applications which can leverage the outstanding performance of the driver IC include telecom and industrial SMPS, DC-DC converters, PFC in electrical vehicle charging stations as well as industrial applications such as AC power tools, UPS, air conditioning and fans. The new family also supports wireless charging applications.
