Re: heatsinking a thermal padded IC ?


Are you familiar with the on-chip diode method to measure die
temperaure? If not, I'll write it up.

Yes, I'd interested. Assuming I find a diode , it'll need to be measured during power up. As John Devereux pointed out, a forward biased ESD protection diode on one of the logic inputs may be my only option.

Is it necessary to do a two point temperature calibration and extrapolate Vd vs T with the diode equation ?
