Embodiment Construction
[0017] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:
[0018] refer to figure 1 , the activation circuit includes a thermal battery pack output control circuit, an activation signal output control circuit (composed of a comparator and an output control circuit) and a reference voltage output control circuit. The thermal battery cell 1 is activated by an external activation signal, and the output of the thermal battery cell 1 is output as a thermal battery pack output through the thermal battery pack output control circuit. The output of the thermal battery cell 1 and the output of the thermal battery pack are connected to the input terminal of the reference voltage output control circuit 1, and the reference voltage output control circuit 1 outputs the reference voltage to the non-inverting input terminal of the comparator 1, and the output of the thermal battery pack is divided and then connected to input to the in...
