Product description
PWM chopper type bipolar stepper motor driver IC
TB6600HQ/HG is a single chip PWM chopper type bipolar sinusoidal stepper motor subdivision driver.
Can control 2 phase stepper motor forward and reverse rotation,
With 1-2, W1 -2 2W1 -2 4W1 phase, -2 phase excitation mode.
Only the clock pulse signal can drive two-phase bipolar stepper motor to achieve low vibration, high efficiency work.

The TB6600HQ/HG output current setting and protection mode selection:
TB6600HQ/HG output current setting mode:
The maximum current magnitude of the TB6600 output is determined by the Vref (pin5) and the sampling resistance (Rnf), and the formula is as follows:
Io = (1/3 * Vref), RNF
Namely: =Vref output current (voltage reference) / 3 / sampling resistance
Such as: Rnf=0.4, Vref=3V, then Io=2.5A
Note: the average current is lower than the theoretical value, because the nominal current value of the step system is the peak value.
RNF (sampling resistance) should be greater than or equal to 0.2.
Protection and over current protection mode selection:
L: blocking mode --- that is, in the case of overheating or over current, the chip to enter the protection mode, turn off the output. Recommend using this mode
H: self recovery mode --- that is, in the case of overheating or over current, chip protection and automatic recovery, such as the error state has always existed, the chip cycle in the protection - recovery of two states, please try to avoid the use of this model
Comparison of TB6600HQ/HG and TB6560AHQ shape
TB6600 is considered to be the upgrading of TB6560AHQ products, the maximum voltage 5A current 50V, and joined the overcurrent protection function, and only a single road power supply. Although the driving ability to enhance a lot, but relying on the latest BiCD0.13 technology, the volume of TB6600 is smaller than TB6560.
