The 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
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 monitor pins (DOWN / ALERT)
Equipped with reset and enable pins
Built-in thermal shutdown(TSD) and over-current detection(ISD) circuit

Parameter
High output withstand voltage: VDSS 50 V
High output current: Iout 4.5 A (peak)
Packages: HZIP25-P-1.27
Dementions:3.6*1.4*0.5 cm
Weight:9.86g

dear jerry,
congrats for such a good product. I think you should put some units of it on the ebay. I bet it is going to be a perfect replacement for stk series drivers( i think they are uni-polar). As you said it has built-in thermal and o-current protection, it will be a long life solution for the diy'rs.
Why don't you make a successfull stepper driver with that and put the complete schematic here. It is going to make a perfect driver for nema 23 size motors.

Dear,

Thanks for your comments.:cheers:
THB6064AH offers simple peripheral circuit, more selectable phase excitation, high output current and high driver voltage, as TB6560. Its excellent performance is a quantum leap ahead of TA8435 AND TB6560HQ.Therefore, it is an updated product.

Schematic has 2 lines free floating - is that incomplete or something?
Board image is missing internal layers?

Pretty pls if possible post better resolution / clearer / higher resolution images for these - schematic and board image, thank you very much.

Dear,

pin1、4 are NC. Pin7 is base of triode.Pin 7 can pull up to VCC or free float.

You can refer the datasheet of 6n137.

is this still alive?

is there overcurrent protection? adjustable? i dont see any VR

[lucas]

Yes, but you have to look in the appropriate forums:

The chip has overcurrent protection and a VR to set the motor current to whatever value you want, not limited to specific currents using jumpers.
