<p><P>PROBLEM TO BE SOLVED: To provide a control circuit having a small number of components and a small number of using ports of a microcomputer. <P>SOLUTION: This control circuit for controlling the temperature of a measuring object based on a signal detected by a thermometric resistance part is equipped with a current adjusting circuit for outputting a burnout current to a thermometric resistor; a CPU outputting a high-level or low-level voltage to the current adjusting circuit, or equipped with a burnout control port showing a high impedance; and a voltage regulator for generating an intermediate potential between two kinds of potentials operating the CPU. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
