The Solid-sense switch circuit to protect person and equipment is as shown Figure 1 When the temperature of chip reaches the high set-value or low set-value, the TSC620 temperature sensing switch (produced by the Tai Leda Solid Components Inc.)is sensed by the program. When it reaches the high set-value, MOSFET turns on and then the fan. When it reaches the low set-value, it will shut down.
