Conducting, the voltage of the input terminal 8222 of switching tube 822 are the low-voltage of ground connection.When magnetic resistance resistance 81 and second resistance 823 together
When the voltage got is lower than the conducting voltage of switching tube 822, switching tube 822 is in an off state, the input terminal of switching tube 822
8222 disconnect with output end 8223, and the voltage of the input terminal 8222 of switching tube 822 is the high level voltage of power Vcc.Switching tube
822 input terminal 8222 is the output end of the first detection circuit 82 and the output end of sensor circuit 80.In this implement scene

Lu Zhong plays the role of protecting circuit.
Therefore, it can be leaned on by the resistance value of adjusting first resistor 821 and second resistance 823 so that magnetic resistance resistance 81 is in
When the state of nearly magnetic cell, the voltage that magnetic resistance resistance 81 and second resistance 823 can get is greater than or equal to leading for switching tube 822
Be powered pressure, and when magnetic resistance resistance 81 is in the state far from magnetic cell, the electricity that magnetic resistance resistance 81 and second resistance 823 can get
Pressure is less than the conducting voltage of switching tube 822.In this way when the resistance value of magnetic resistance resistance 81 is greater than preset threshold, switching tube 822 is in
On state, the low level voltage of the input terminal 8222 of switching tube 822 are the first starting-up signal.When the resistance value of magnetic resistance resistance 81 is small
When preset threshold, switching tube 822 is in an off state, and the high level voltage of the input terminal 8222 of switching tube 822 is the first pass
Machine signal.
Further, in order to reduce power consumption, the very big resistance of resistance value may be selected (such as in second resistance 823 and 3rd resistor 824
Several hundred k Ω ranks), so that the current limit of second resistance 823 and 3rd resistor 824 will be flowed through to very little (uA rank), R1 is same
Reason reduces power consumption to reduce electric current as far as possible.
As can be seen from the above description, in the present embodiment, protection circuit is played by addition second resistance and 3rd resistor,
The excessive damage sensor circuit of Current Voltage is prevented, the resistance value height of second resistance and 3rd resistor can reduce electric current, reduce function
Consumption.
