A linear ASIC library typically contains voltage references and comparators as standard cells. These cells in concert with a unique NTC (Negative Temperature Coefficient) cell provide overtemperature detection which is used for thermal shutdown of an integrated system. The block diagram in Fig. 1 shows how the NTC cell is used for thermal shutdown.
