If so why only p mos?

A good question.

This what the OP states, again we are working with limited information.

hi Sarma,
As its a R/C toy car, I suspect those 6.5uH inductors are for radio RF suppression.

From the initial tests I have done, it appears that theP MOS fets are failing at power on due to poor circuit design.?

How about something with low ESR like a few ceramic caps?? How far away are they?

I saw it Eric, but he forgot that the inductors he used in series are enough to create the back emf. perhaps the motor is substituted by the combination of these inductors and the 11 ohm.
However 5.6uH is too small to be expected as Motor simulator.

Hi Eric
these inductors in series with motor are only for radio RF suppression.I don't know what happen on your testing?Could you show me more detail information?
