Voltage Jumper, Creepage Distance for Gate Driver 1EDI20I12AF

Anurag · ‎Mar 02, 2023

Hello,

We are developing a high voltage (450V to 850V) BLDC driver for electric vehicles,

Using IGBT driver, PN 1EDI20I12AF.

We have a technical question:

As the IC is suitable upto 1200V, the high side drive will have Ground reference of High Voltage (850V) on pin 8,

while the Pin 7 is just 0.65 mm far, Pin 2 is 4.5 mm far,

How does it pass the creepage test?

Doesn't the voltage jump to other neighbouring pins?

Please help us clarify this point.

Hi Anurag：

Thanks for your reference, 1EDI20I12AF is not automotive gate drive IC. Would you like double check it?

This is list for your application:

Would you please cloose "active and preferred" "automotive" product for your design.
