On chip photoelectric encoder interface circuit; 16 channel A / D converter(6374 motor 190kv). Its function is to wait until the three upper drive outputs have indeed turned into high-level state before allowing the three lower drive outputs to turn into high-level state, so as to avoid the risk of simultaneous conduction of the upper and lower switches of the inverter bridge(6354 motor), so as to change the pulse width of the high or low level in the unit cycle and generate PWM waveform.

Fast closing of PWM channel(6374 brushless outrunner motor); programmable PWM dead time control to prevent the upper and lower bridge arms from outputting trigger pulse at the same time; 3 capture units; event manager module is applicable to control AC induction motor, BLDCM, SRM, stepping motor, multipole motor and inverter(6354 180kv). Expandable external program memory, 192K words in total; 64K words program memory space; 64K words data memory space.
The frequency of DSP is provided by the external 10MHz crystal oscillator(6374 motor). The circuit of rotor position detection is designed in the control system of BLDCM. On the one hand, the position sensor is used to measure the position of rotor pole and provide information for the realization of electronic commutation(6354 outrunner motor); on the other hand, it is used to detect motor speed and provide real-time speed for closed-loop speed feedback.
Its shape is similar to that of ordinary small transistors, so as to reliably protect the two power MOS devices of the bridge arm, with small volume and high sensitivity(6384 motor). The amplitude of the signal is the same except that it is different from the original signal. With the development of control theory and the demand of high-performance control(5065 150kv), single chip or multi chip microprocessor can not meet the complex and advanced control algorithm.
In general, Hall effect is used to integrate Hall elements and semiconductor integrated circuits into a n-type silicon epitaxial chip(electric longboard motor). It can be seen from the figure that as long as the value of the comparison register is changed in real time, the time length of the comparison matching event can be changed. After quadrupling the frequency of DSP(skateboard esc), it can provide 40MHz working frequency to ensure the fast operation of DSP to the maximum extent.
To prevent the error of the driving signal and lead to the occurrence of through phenomenon(6384 150kv). But the position sensor signal of the input DSP is the signal after the bus driver converts the 5V level to 3.3V. When the DSP decodes the hall sensor signal, it not only needs to detect the level change of the frost sensor(electric skateboard remote control), but also needs to know whether the level is high or low, so as to judge the position of the rotor; 64K words / O addressing space.
When the output of the user's pulse forming link fails(6374 brushless motor), the IR2130 receives that the gate jerk signals of the upper and lower main switch power devices of the same bridge arm in the converter are all at high level, then the internal design can ensure that the two gate drive signals actually output by the high channel are all at low level(electric longboard esc), according to the determined rotor position and positive Reverse the logic to control the continuity sequence of the windings.
