AC motor drive problem!

I do have a centrifuge 5810. It has faulty rotor driver, after working out on the driver card, I am able to understand design concept of the driver.

It is 3 phase motor, so 3-phase IGBT inverter is used for driving rotor.
the below figure explains the concept.

As shown in the figure there are 6 igbts,(3 pairs), 6 igbt are provided 6 gate inputs, each igbt has a gate driver-A95w...which is gone bad for one igbt..
I am not able to find the details of this component...
It is 8 pin smd ic-A95w written and logo of the company is also mysterious..

after working out on the connection, I found pin 1,3 and 7 of this IC are made short by the manufacturer and further when ic is connected pin 2 also become short to above 3 pins...

Do anyone know this kind of driver??
any details...I am attaching pcb drive image...

Does your camera have a macro focus?

Do u need another image?
tell me what u are doubting...because I don't have that clear image...\
but IC name is A95w and 8 pin soic package and used for IGBT driver(I guess)..
Have u any information about this?
