When extracting pen cap, far from the Magnetic Sensor U1 in magnetic sensor circuit 1, magnetic passes the magnetic force generator in pen cap
Sensor U1 is 0 from that can sense magnetic flux to the magnetic flux sensed less than magnetic flux is incuded, the 3rd pin of Magnetic Sensor U1
The second electric signal is exported, can be from the low level signal got higher.This from the low level signal got higher cause Hall_SW signal from
Low level becomes high level, and Q1_G is low level, therefore, the first metal-oxide-semiconductor Q1 conducting.Since the first metal-oxide-semiconductor Q1 is connected,
The high level of Hall_SW reaches the grid of the second metal-oxide-semiconductor Q2 by the first metal-oxide-semiconductor Q1, at this point, the Q2_G (grid of the second metal-oxide-semiconductor Q2
Pole) it gets higher, the second metal-oxide-semiconductor Q2 conducting.The switching on and shutting down pin POWER_ON/OFF of on/off circuit 2 is pulled low, power management core
Piece powers on, and pen starting, the logic of the working condition of pen becomes 1 from 0.

Electric signal, but the second electric signal exported no longer influences the switching on and shutting down pin of on/off circuit 2, i.e. power management chip continues
Working condition before holding, powers on or lower electricity continues to use that is, if pen is in use, if pen does not have to and oneself for a long time
Dynamic shutdown, continues to remain turned off state.
When the logic of the working condition of pen is 1, i.e., when pen is in running order, when plugging pen cap, Magnetic Sensor
U1 is zero to that can sense magnetic flux from the magnetic flux sensed, and third pin exports the first electric signal, and Hall_SW signal is
Second electric signal, i.e., the signal being lower by height, for example become 0 level from 1, at this point, control chip receives this and becomes 0 from 1
Level after, by being communicated between power management chip, control the closing that electricity under power management chip realizes pen, pen
The logic of working condition becomes 0 from 1.
Wherein, the logic of the working condition of pen is that 1 expression pen is in running order, and the logic of the working condition of pen is 0 table
Show that pen is in close state.
After extracting pen cap, pen places a period of time without meeting automatic shutdown, and the Magnetic Sensor U1 in inductive switch feels
When should be less than magnetic flux, output high level can be continued, so that postboost pen is switched on once more, thus cannot achieve really
Shutdown, power consumption is larger, and the trigger control circuit for starting or closing by application pen provided by the utility model, avoids pen and opens
