Embodiment Construction
[0035] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary, and embodiments of the present invention are described in detail below.
[0036] Such as figure 1 Shown is a wearing detection circuit that is prone to false triggers in the prior art, where EMS_OUT1 and EMS_OUT2 are electrode pads, and EMS_CHECK1 is at high level when not wearing; after wearing, EMS_CHECK1 is at low level.
[0037] However, technicians found that since the value of VCC_HV1 will change greatly in a very short period of time, and the frequency of turning on and off of the triode is very high, it is easy to generate interference in the circuit and cause false detection. Specifically, when the user is not wearing it, for the electrode drive circuit terminal, when the CA terminal is closed and the CB terminal is opened, the charge accumulated on the emitter of the first triode will move to VB with the opening of the...
