I have a design where I used to use the L6202's...  probably a total of 
100pcs/month.   And, they were pretty much the leading cause of failures 
and rmas.   Like probably a 3-4% lifetime failure rate.  A couple of 
years ago, I switched to the LMD18200 and have yet to see a failed 
LM18200.  Ever.   I haven't even been able to kill one on the bench when 
abusing it on purpose.   Of course I didn't do something like put 
thousands of volts through it, but things like dead shorts don't even 
make the thing blink.

Of course, I buy them 250 or 500 at a time so the price isn't quite as 
bad as the $18 in singles...    Still hurt but worth every penny.
