Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect,
Below in conjunction with specific embodiment, the present invention is expanded on further.
As it is shown in figure 1, a kind of novel resetting wake-up circuit, comprising: master chip control circuit 1 and being connected to
The waking up input circuit 2 up, wake up output circuit 3 up of described master chip control circuit.
Wherein, seeing Fig. 2, master chip control circuit uses STM32F030F4 chip, this STM32F030F4
1 foot of chip passes through resistance R13 ground connection, and 2 feet, 3 feet, 7-10 foot, 11-14 foot, 17-20 foot are empty
Pin, 4 feet pass through electric capacity C8 ground connection, and, 4 feet are connected to power supply VCC by resistance R16, and 5 feet are connected to
Power supply VCC, 6 feet connect the interface MO_WKUP waking up input, output circuit up, 15 foot ground connection, and 16 feet are connected to electricity
Source VCC.
Shown in Figure 4, described in wake up input circuit 2 up and include: be connected to successively the electric capacity C5 of button key, two
Pole pipe D2, this button key are connected to power supply AVCC, and the other end of described diode D2 is connected to master chip control
Circuit, the two of described electric capacity C5 are terminated with the resistance R10 of ground connection, resistance R11, described diode D2 respectively
Outfan is connected to the resistance R12 of ground connection, electric capacity C6 respectively.
Shown in Figure 3, use the output circuit 3 that wakes up up of IMP811TEUS chip to include: to be connected to master chip
The resistance R1 (playing metering function) of control circuit, described resistance R1 are connected to audion Q1 and (play switch to make
With), the grounded emitter of this audion Q1, the colelctor electrode of audion is connected to 3 feet of control chip U2, control
It is connected to be connected to power supply AVCC between 3 feet and the transistor collector of coremaking sheet (using IMP811TEUS chip)
Resistance R2 (playing pull-up effect), 4 feet of control chip U2 are connected to power supply AVCC, and control chip U2
