【Outline】
The TB6605FTG is a pre-driver for 3 phase brushless DC motor. BiCD process is adopted.
Maximum ratings of motor drive voltage is 30V and operating range is up to 28V.
This evaluation board mounts necessary components to evaluate the motor. And uses 8A
and 30V ratings Nch type MOS FET as output.
Connecting external hall elements and motor to this board, it’s possible to control motor.
Please try the controllability of a brushless DC motor by applying the TB6605FTG.
【Note】
In using, please be careful about the thermal condition sufficiently.
For each control signal, please refer to the IC specifications by accessing to the following
URL:

Further, the application of this evaluation board is limited to the purpose of evaluating and
learning the motor control. Please do not ship them to a market.

(Note 1): Please adjust R6 resistor value to fit current limiter target value.
(Current limit value) : 0.1Ωis mounted on this board. Iout (max) = 0.25V / R6 = 2.5A
(Note 2): Please adjust lock protection setting used R3 and R4 resistor value.
In this board, 68kΩis mounted as R3, and 33kΩis mounted as R4. It becomes automatic recovery mode,
and lock detection time is 1s.

）: Switches are used for OVP pin, BRAKE pin, CW/CCW pin and START pin settings.
Power ON sequence
1. In general, please set BRAKE switch to high level.
2. During start operation, please hold inputting PWM signal as low level.
3. On next step, please set to START switch to high level.
4. In case of motor drive voltage is 24V, please set to OVP pin to high
level. In case of motor drive voltage is 12V, please set to OVP pin to
low level.
5. Please supply VCC voltage (VCC voltage range is 9 to 28V.)
6. Please set to START switch as low level. (Motor starts operation.)
7. When PWM signal(speed control signal) inputs to PWM-in pin, a
motor speed changes based on PWM signal.
Switch name Pin name High/Low Explanation
SW1 OVP High Motor drive voltage：24V
Low Motor drive voltage：12V
SW2 BRAKE High Operation
Low Brake
SW3 CW/CCW High Reverse
Low Forward
SW4 START High Stop (Charge Pump circuit is stopped）
Low Operation (Charge Pump circuit is operation)
Power OFF sequence
1. Down PWM duty slowly, and stop
the motor rotation.
2. Set START switch to high level
position.
3. Fixed PWM signal to low level.
4. Power OFF of VCC power supply.

The method of JP(Jumper) usage
JP name Related pins Initial status Comments
JP2 P+、P- Open It used for power supply connector of hall elements.
JP4 OUT-A
OUT-B
OUT-C
Open It uses for motor connector.
OUT - A pin , OUT - B pin, OUT - C pin are connected based on silk
indication.
JP9 VCC Short It must use with short condition. Supplies to power of FET and hall elements.
JP10 VREG,VREG1 Short Please use it with short condition, basically.
When JP10 is shorted, VREF supplies to the power for pull up.
