Notice: Product End Of Life. Not recommended for new designs Our THB6064AH driver supports BiPolar motors up to 4 amps/phase at 50 volts... CONTINUOUS!. New version 1.3 is simpler, less expensive, with top quality for critical parts. Based on the THB6064AH chip (also known as the Toshiba TB6564AHQ^) which is a design improvement over the TB6560, with better microstepping, lower resonance, and protection for power on sequence (which is a serious problem with the 6560). Features: 4.5 Amps (peak) and 4 Amp sustained at 50 volts. And unlike the cheap drivers advertised at only peak ratings elsewhere, it WILL drive 4A @ 50V = 200Watts continuously. ^ Micro-step: 1/2,1/8,1/10, 1/16, 1/20, 1/32, 1/40, 1/64 step Compatible: 2.3uS Step pulse response. With slight pulse stretch provided by the PCB, this driver will work with the Marlin based RAMPs controllers for 3D printers. Video proof. Now you can build a 3D printer big enough to extrude a house! Reliable: Built-in thermal shutdown (TSD) and over-current detection (ISD) as well as back EMF protection. Unlike the TB6560, which absolutely requires logic power be stable before motor power is applied,^ the THB6064AH can survive motor power without logic power and will not intermittently short on power up. This is a VERY common failure of the cheap TB6560 drives. ^ Repairable: HZIP25-P-1.27 package is easy to solder and desolder for replacement. Cool: Automatic idle drive power reduction. Efficient: 4 decay modes from 20 to 80%. High voltage BiCD process: Ron = 0.4 (typ.) Standard: Step / Direction inputs work with any controller. Optional reset and enable. Output monitor pins (DOWN / ALERT). NOTE: This is a Kit of parts; you must solder it together. Although easy and well documented, if you haven`t soldered before, please complete our soldering course and the 2 (low cost) projects it suggests before attempting this driver. This kit does not include heatsink, main or logic power supply, motors, or wiring. SPECIAL PROMOTION (for a limited time): Buy the full parts kit (not for the PCB / chip only options) at the standard price, build it, and then send us your results or post publicly online. We will pay you back $5 for a photo of it up and running. $20 for a video. $10 for a write up including your power supply voltage, motor rating (amps/phase, size, rated torque, etc...) and your review of how it worked (or didn`t) and what you liked (or hated) about the kit. Do all three and the kit is free!
