Title: Circuit for protecting semiconductor integrated circuit from overheat
Inventor: TANAKA JUN
IPC: H01L23/58
Filed: 1994-04-27
Abstract: PURPOSE:To obtain an overheat protecting circuit, which is not erroneously operated under the state, that the operating temperature of an IC is in the vicinity of the starting temperature of overheat protecting operation. CONSTITUTION:A circuit for protecting an IC from overheat has a temperature monitoring circuit 1 for detecting the temperature of the IC, a monitored-result outputting circuit 2 for outputting the detected result of the temperature monitoring circuit 1, a discriminating circuit 3, which transmits only the output in a certain specified time among the outputs of the monitored result outputting circuit 2 to a signal generating circuit 4, and the signal generating circuit 4, which receives the signal from the discriminating circuit 3 and extends the output. Therefore, the discriminating circuit 3 prevents the overheat protection caused by the malfunction of the circuits 1 and 2 by excluding the output of the monitored-result outputting circuit 2, which is shorter than the specified time. The signal generating circuit 4 can set the temperature of the IC at the temperature which is further lower than the starting temperature of the overheat proteting operation by fixing the output for the specified time even if the temperature at which the overheat protecting operation is released is obtained. Since the overheat protecting state does not appear by the erroneous operation, the stable overheat protecting operation is performed even if the ICs are in the overcrowded mounting state.
