TB6560HQ,TB6560FG
PWM Chopper-Type bipolar
Stepping Motor Driver IC
The TB6560HQ/FG is a PWM chopper-type sinusoidal micro-step
bipolar stepping motor driver IC.
It supports both 2-phase/1-2-phase/W1-2-phase/2W1-2-phase
excitation mode and forward/reverse mode and is capable of
low-vibration, high-performance drive of 2-phase bipolar type
stepping motors using only a clock signal.
