Locating ATTP1 OTP device for a MSI KM4M m/b

I have an MSI KM4M m/b that uses an Attansic ATTP1 Over Temp Protector IC which appears to have died (a power supply also died in the process but I am unsure of cause or effect sequence). I'd like to get a couple of the ICs but am unsure where they might be available. I was wondering if anyone knew of a good source for this device (samples would be greatly appreciated :) Also, a good second source/substitute for the device (Maxim? NSC? Other?) could also be helpful.

Thanks in advance....Step

Thanks for the suggestion. I'll take a look at Microchip and see what they might have.

BTW - The ATTP1 either is the problem or is a casualty of whatever happened (possible PS failure?) for 2 reasons: 1. I checked the *PON line and it has been pulled down by a short that seems to track back to the ATTP1 *PON output and, 2. upon closer visual inspection of the ATTP1 I noticed the silkscreening has been burned off by whatever excessive heat (current) had passed thru the device. :)

Maxim does not send samples unless you are involved in research work or of the sort . Try MICROCHIP but again all these companies do not accept and provide samples for request from generic websites like msn , yahoo etc., I really doubt if this the problem on your mobo
