Cooling Fan Circuits

Circuit protects system from overheating: 11/08/2001 EDN - Design Ideas / The two-chip circuit in Figure 1 provides fan control and overtemperature warning and shutdown signals to protect systems from excessive heat. The circuit monitors the temperature of the pc board and the die temperature of a CPU, an FPGA, or another IC with an on-chip temperature-sensing transistor. .
