We've had a few 'issues' with the ICD2. Only sometimes when you plug it into
the board, the PIC will start drawing loads of current (>400mA), and get
VERY hot (some sort of latch up I expect). Well it happened the other day,
and I got the little hand held IR thermometer we use to find faults on
boards sometimes to see what temperature the PIC was. The thermometer went
over range! >207 deg C!!!!

I turned off the power, let the PIC cool down, powered it up again and it
ran as normal!!!!!

Hi all,
I've just finished testing my new PIC programmer (yes, the breadboarded test
model works) and my switchmode PSU just died. Not dead as in no output, but
dead as in 20V straight over the 5V output. Unbelievably, the PIC16F628 that
was connected to the output of said PSU is still working!
It looks like the PIC's ESD protection kicked in and protected it. Well,
that's the best explanation I've got ATM. The 7407 buffer and MAX662 voltage
booster seem to be fine, too. Has anyone ever had a similar experience with
a PIC?
