The start module 32 has a first input end connected with the power supply module 31, a second input end connected with the MCU 2, and is used to generate a start voltage signal after receiving the start signal of the MCU 2 and the first voltage signal of the power supply module 31; and has an output end connected with the LDO 4, and is used to send the start voltage signal to the LDO 4 to start the LDO 4.

[0072] Specifically, the startup module 32 includes a first filter unit 321, a second filter unit 322, a first switch unit 324, and a third filter unit 323. The first filter unit 321 has an input connected to the power module 31 for receiving a first voltage signal from the power module 31, filtering the first voltage signal, and generating a second voltage signal. Its output is connected to the first end of the first switch unit 324 for sending the second voltage signal to the first switch unit 324. The second filter unit 322 has an input connected to the MCU2 for receiving a startup signal from the MCU2, filtering the startup signal, and generating a first startup signal. Its output is connected to the second end of the first switch unit 324 for sending the first startup signal to the first switch unit 324. The first switch unit 324 has a first end connected to the first filter unit 321 for receiving the second voltage signal. Its second end is connected to the second filter unit 322 for receiving the first startup signal and generating a third voltage signal after receiving the first startup signal and the second voltage signal.

Through the above setting, the noise in the signal sent by the MCU2 can be filtered out, the smooth transmission of the signal is ensured, and the filtered signal is sent to the first switch unit 324.

[0076] Specifically, the first switch unit 324 includes a P-type first MOS tube 3241, a fourth resistor 3242 and a P-type second MOS tube 3243. Wherein the source of the first MOS tube 3241 is connected with the first end of the first capacitor 3212, the drain is connected with the third filter unit 323, and the gate is connected with the second end of the first capacitor 3212.

Through the above third filter unit 323, the noise of the signal output by the first switch unit 324 can be removed.

[0078] Through the above setting, when the MCU2 sends a start signal, the second filter unit 322 filters the start signal and generates a first start signal, which is sent to the second MOS tube 3243, so that the second MOS tube 3243 is turned on.
