When lit, indicates that power is being supplied to the
PIC24FJ256GB106 MCU via the USB and the target MCU
may be set to operate in Debug mode.
Controls the programming/debugging operations of the target
dsPIC33FJ16MC102 DSC.
Provides system power and bidirectional communication
between the host PC and starter kit.
Figure 1-1
Provides the processing power for the demonstration applica-
tions and application development on the starter kit. The
MCU features 16 Kbytes of Flash program memory and
1 Kbyte of RAM. The demonstration application uses the
MCU’s on-chip FRC oscillator with PLL as a clock source.
The BLDC Motor is connected to the starter kit board via a
6-pin connector. The three phases of the motor are
connected to pins 1, 2, and 3 while the other pins are left
unconnected.
A 9V power supply powers the dsPIC33FJ16MC102 DSC
and the motor control circuitry on the starter kit. To operate
the starter kit, connect the power supply provided with the
starter kit (AC162039) to J3.
Microchip’s TC4428 dual MOSFET drivers provide the inter-
face between the low-voltage control side, the
dsPIC33FJ16MC102 DSC, and the power side of the applica-
tion (i.e., MOSFETs). These drivers provide the MOSFETs
with current as well as the proper voltage, inverting the
high-side PWM to drive the P-channel MOSFET, while keep-
ing the delay time equal to the N-channel MOSFET.
The 3-phase inverter features three half-bridges implemented
with dual N- and P-Channel MOSFETs. While the MOSFETs
are capable of driving higher currents, the 10W power supply
limits the maximum current to approximately 800 mA. At this
power level, there is no need for an external heat sink.
A 3-phase BLDC motor is provided with the Motor Control
Starter Kit (Shinano DR-29312). The motor specifications are
