DrMOS CPU gate driver chip - random shutdowns?

One person from eBay told me the problem with almost EVERY MacBook Pro 15 2013 is that: “DrMOS CPU gate driver chips” and repair is £150.

Is that true - tried to google that words - no success

Here is our problem with MacBooks —-> Why does an external display prevent my MBP from freezing & crashing?

I think (because MacBook is on so far for about few hours) - final release Mojave and clean install fixed problem.

Crazy think - under clean Beta 11 I still had shutdowns - I kind-of-fix them with disabling Thunderbolt drivers.

So far so good

I don’t see the connection of the DrMOS chips with the external Thunderbolt display connection effecting things.

Why would power regulation to the CPU be effected by having an external monitor connected?

Keep in mind the external is needed to prevent the crash not cause it! I could see the added load would have effected things by thats not the case here just the reverse.

Bart are you also having the same issue? If you are I’ve had a few boards which needed a new Thunderbolt chip thats the only thing I’ve seen related to having an external monitor plugged in. I’ve also seen a few blown TB chips as well (early revs).

ok Dan - so Thunderbolt chip is the same for HDMI output? As connected through HDMI prevents from shutdowns as well

There is a different chip that drives the output to the HDMI its U9750 (HD3SS213ZQE) is the differential switch it mux's the video signal to either the HDMI or internal DP or DP (Thunderbolt) circuitry.
