Power supply.Diode Z1 is connected in parallel on U1 input, there is provided overvoltage protection.R4, R5 are connected to VCC by D1, to be pulled upward to power supply, from
And limit electric current.When U1 outputs are high level, Q3 cut-offs, Q4 conductings（Now, Q4 ce junction voltages just only have 0.3V, and Q3
Be knots be reverse-biased, therefore Q3 can not be turned on）, electric current through R7 → D2 → D3 → D4 → Q4 colelctor electrodes-emitter stage →
GND, while electric current is through R7 → Q6 base-emitters → D6 → R11 → R12 → ground terminal（GND）, Q6 conductings, now R12 two
Terminal voltage is output voltage OUT when toppling over.When U1 outputs are low level, Q4 cut-offs, Q3 conductings（Because U1 low level only has
0.3V, Q4 can not be turned on, would not be the voltage pull-down of Q3 emitter stages, Q3 be knot positively biaseds, Q3 conductings）, electric current is through R7
→ D2 → D3 → D4 → D5 → Q3 emitter stages-colelctor electrode → GND, at the same electric current through R7 → Q6 base-emitters → D6 → R11 →
R12 → GND, Q6 are turned on, output voltage OUT when now R12 both end voltages are upright.Its output voltage curve, as shown in figure 4,
Supply voltage scope is from 9-16V：
When upright, S pole fields influence Hall, Hall output about 0.1-0.3V（Low level）, Q4 cut-offs, Q3, Q6 work
In emitter follower state.OUT output voltages are：
VOUT（It is upright）=(VQ3CB+VQ3BE+VD2+VD3+VD4+VD5-VQ6BE-VD6) * (load resistance //R12)/
(R11+ load resistances //R12), VQ3CB voltages=supply voltage-VD1-VZ2；Only have supply voltage linearly to become from 9-16 among these
Change, so being oblique line when upright.
During inclination, S pole fields no longer influence Hall, and Hall output is high level, and Q3 ends, and Q6 is operated in emitter follower
State, Q4 saturation conductions.OUT output voltages are：
VOUT（Tilt）=（VD2+VD3+VD4+VQ4CE-VQ6BE-VD6）* (load resistance //R12)/(R11+ loads electricity
Resistance //R12), mains voltage variations would not influence this output voltage during inclination.
Above-mentioned output voltage is the effect as caused by high level change-over circuit and low transition circuit.
Protected during misconnection：
OUT and GND are reversed, and supply voltage is accessed by VCC, be knots → R3 → R12 → GND through Q2, while Q5 conductings →
Q1 is turned on；Q2 can undergo the process for first turning on and ending afterwards, and subsequent conditioning circuit power supply is disconnected, it is achieved thereby that protection during misconnection；
Now OUT exports low level, allows motorcycle to stop working.
VCC and GND are reversed：Supply voltage is through R9 → load equivalent resistance → GND, while the be through R13 → Q5 is tied → born
Equivalent resistance → GND is carried, now OUT exports low level, allows motorcycle to stop working.
VCC and OUT are reversed：Supply voltage reverse breakdown Q5 be knots → R11 → R10 → load equivalent resistance → GND, this
When OUT output low level, allow motorcycle to stop working.
