Triggering circuit, start trigger circuit triggers switch driving circuit power-on switch Q1, input power VIN are conducting to out-put supply
VOUT, completes start and triggers, and now intelligent processor system starts, intelligent processor detects that switching on and shutting down button is pressed
(POWER_KEYIN signal low level) maintains (output high level to POWER_ON/nOFF), system more than performing start during 0.5S
Having powered on short by soft start, otherwise, do not performed start and maintain, system just cannot complete start.
Software controls shutdown: open state presses switching on and shutting down button, and intelligent processor detects that switching on and shutting down signal produces electricity
When road output low level (representing switching on and shutting down button down state) is more than 2S, closed by UI (liquid crystal, LED etc.) prompting user
Machine, then user understands trip switch machine button, and intelligent processor can detect that switching on and shutting down signal generating circuit exports high level (table
Show switching on and shutting down button releasing orientation), i.e. perform shutdown action (output low level to POWER_ON/nOFF), system power failure completes
Length presses soft-off.
Hardware controls is shut down: open state presses switching on and shutting down button, is always maintained at pinning until exceeding Long-time-delay circuit and setting
Fixed time constant, Long-time-delay circuit triggers the work of hardware circuit for forced shutdown, power cutoff switch Q1, completes hardware and force to close
Machine.
It is on the practice processes being described above as in the embodiment of figure 2, switching on and shutting down working power is produced circuit
With switching on and shutting down signal generating circuit do equivalence change and come, circuit structure is more simplified.
