Hi Kai, I have seen HIN232 (intersil) surviving even 12V but I quickly disconnected it within 5-10 seconds .
Surviving? how do you know that the clamping diodes did not pop - how do you know that the chip was not "weakened but still somehow working" Erik again: that fact that something "works" does not prove it is OK" |
