PWM Chopper-Type bipolar
Stepping Motor Driver IC
The TB6564AHQ(THB6064AH) is a PWM chopper-type
sinusoidal micro-step bipolar stepping motor driver IC.
It supports 8 kind of excitation modes 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.
Features
• Single-chip bipolar sinusoidal micro-step stepping motor
driver
• Uses high withstand voltage BiCD process:
Ron (upper  lower) = 0.4 Ω (typ.)
• Forward and reverse rotation control available
• Selectable phase drive (1/2,1/8,1/10, 1/16, 1/20, 1/32, 1/40, 1/64 step)
• Output withstand voltage: VDSS = 50 V
• Output current: IOUT = 4.5 A (absolute maximum ratings, peak, within 100ms)
IOUT = 4.0 A (operating range, maximal value)
• Packages: HZIP25-P-1.27
• Output monitor pins (DOWN / ALERT)
• Equipped with reset and enable pins
• Built-in thermal shutdown(TSD) and over-current detection(ISD) circuit
