    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

    It sounds a great chip.Has anyone tested it? I think you can show more information,as picture,pins schematic diagram?If not, it has a trust issue. And that is a serious problem.

    Don't worry "Christina", I rather suspect your request will trigger lots of information including pictures and schematic diagrams :rofl:

    They look worth trying - not far from the spec. of the M542 series drivers. It depends if 50V is the absolute maximum voltage or recommended...

    Thanks Jonathan.

    It's very interesting that a guy is testing THB6064AH,and he post the results there.It's good news for all that are interested in this kind chip with doubt like me.

    Maybe I should have a try after he completes it.

    THB6064is customized product designedBeijing Haihua Boyuan Science Technology and Development Co.,Ltd and produced by TOSHIBA Semiconductor Company. In TOSHIBA company, it has an internal model (TB6564AHQ), so you can’t find any documents about THB6064AH.However, you can find the announcement about THB series chip by TOSHIBA Semiconductor Co.Ltd.
