Preliminary
TOSHIBA BiCD Integrated Circuit Silicon Monolithic
TB6600HQ
PWM Chopper-Type bipolar
Stepping Motor Driver IC
TB6600HQ
The TB6600HQ is a PWM chopper-type single-chip bipolar sinusoidal
micro-step stepping motor driver.
Forward and reverse rotation control is available with 2-phase,
1-2-phase, W1-2-phase, 2W1-2-phase, and 4W1-2-phase excitation
modes.
2-phase bipolar-type stepping motor can be driven by only clock signal
with low vibration and high efficiency.
