![]() I have used the DM556 drivers for my DIY CNC router and they have been working great for several years. They can be wired and controlled in the same way as the TB6600, so you can easily upgrade your system later. Digital drivers usually give much better performance and quieter operation. In recent years, digital drivers like the DM556 or DM542 have become much more affordable. Note that the TB6600 is an analog driver. You can find the datasheet for the TB67S109AFTG below. So should you be going for a genuine TB6600 or the ‘upgrade’? I would say it depends on whether you really need the high current output or if you rather prefer up to 1/32 microstepping. Jim from embeddedtronicsblog did some testing on the TB67S109AFTG drivers and found that the stepper motors ran nicer than with the TB6600 drivers. You can tell it uses the TB6600HG chip from the pins sticking out of the PCB and it also only goes up to 1/16 microstepping. You can buy genuine TB6600 drivers on Amazon, like this 4-axis driver board but most use the TB67S109AFTG chip. Below you can find links to the chips on which shows that the TB67S109AFTG is around $1.50 cheaper. The main reason manufacturers switched over to this other chip is probably price. There is a very simple way to check if your driver uses a TB6600HG chip or a TB67S109AFTG chip, the TB6600HG only supports up to 1/16 microstepping (see datasheet), whereas the TB67S109AFTG goes to 1/32. The performance and specifications of these chips are similar, but the TB6600HG does have a higher peak current rating (up to 5 A) and it is just a much larger chip with better heatsinking overall. Instead, it used a much smaller TB67S109AFTG chip, also made by Toshiba. I recently took apart one of the TB6600 drivers I ordered and found out that it didn’t actually use a TB6600HG chip. Low-voltage shutdown, overheating and over-current protectionġ These are the specifications for the TB6600HG IC, the driver itself has a maximum current rating of 3.5 A and 4.0 A peak.Ģ See comment on fake/upgraded TB6600 drivers below.įor more information, you can check out the datasheet and manual below: ![]() Always take a look at the datasheet of your particular driver, before connecting power. Note that the exact specifications and dimensions can differ slightly between manufacturers. You can find more specifications in the table below. The driver has several safety functions built-in like over-current, under-voltage shutdown, and overheating protection. Make sure that you do not connect stepper motors with a current rating of more than 3.5 A to the driver. With a maximum current of 3.5 A continuous, the TB6600 driver can be used to control quite large stepper motors like a NEMA 23. The TB6600 microstepping driver is built around the Toshiba TB6600HG IC and it can be used to drive two-phase bipolar stepper motors.
