PiBot TB6600 Stepper Driver


The PiBot TB6600 Stepper Driver is a [TOSHIBA TB6600HQ] based driver.

  • Features of stepper Driver
    • PWM chopper-type single-chip bipolar sinusoidal micro-step stepping motor driver.
    • BiCD 0.13 (50 V) process, Lower Ron: 0.4 Ω(typ.).
    • Output withstand voltage: VCC = 50 V.
    • Output current: IOUT = 5.0 A (absolute maximum ratings, peak, within 100ms);IOUT = 4.5 A (operating range, maximal. value);More Stepper motor can choose. Solder 6*1W external resister sensor.
    • Thermal shut down (TSD) protection.
    • Under voltage lock out (UVLO) protection.
    • Over-current detection (ISD) protection.
    • Double input port: Anti-reverse structure IDC haeder( 8pin symmetrical input) & HT-396-4pin input (suit for DIY).
    • Stepless adjustable reference voltage.
    • Compatible the CNC Stepper Motor.
    • Offer an solution to change your CNC to 3D Printer.
    • Board size: 51.1*58.5mm ; fix hole: 43.9*45.7mm -Carry 60*60*10mm aluminum Heat sink which build-in fix hole and connection hole.
    • Auto half current, energy conservation.
    • Photoelectric-isolation used in the input port,compatible more drive Level.
    • Programmable micro step - 1/1, 1/2A, 1/2B, 1/4, 1/8, 1/16.
    • Any idea to develop this motor driver, you can ask us.

100% Current Settings (Current value)

100% current value is determined by Vref inputted from external part and the external resistance for detecting output current. Vref is doubled 1/3 inside IC. Per the [TB6600 datasheet], the calculation for current is:

  Io(100%) = (1/3 × Vref) ÷ RNF

The average current is lower than the calculated value because this IC has the method of peak current detection.

RNF should be 0.68||0.68||0.68=0.2267Ω

Sometimes this value can be set by experiment, that Stepper motor not heating, small noise and the chip do not get too hot.
