Programmer/
Debugger Power LED

D2

10

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.

On-board Programmer/
Debugger

N/A

2

Controls the programming/debugging operations of the target 
dsPIC33FJ16MC102 DSC.

Programmer/
Debugger USB 
Connector

J1

3

Provides system power and bidirectional communication 
between the host PC and starter kit.

dsPIC33FJ16MC102 
DSC

U4

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.

Motor Connector

J5

2

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.

9V Power Connector

J3

3

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.

3-Phase Inverter

N/A

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.

BLDC Motor

A 3-phase BLDC motor is provided with the Motor Control 
Starter Kit (Shinano DR-29312). The motor specifications are
