40V/2.0A Constant current two-phase bipolar stepping motor driver IC
Operates without an external sense resistor, integrated in the Stepper 17 Click board™ from Mikroe
The TB67S539FTG is a stepping motor driver IC capable of constant current motor control without an external current sense resistor as the current detector is integrated within the 5.0mm x 5.0mm QFN32 package. In addition, the TB67S539FTG does not require an external capacitor for the charge pump as it is also integrated. With this high level of integration, the need for PCB space is significantly reduced, making it suited to a wide range of constant current control stepper motor applications. Based upon Toshiba’s latest BiCD process, TB67S539FTG is capable of driving bipolar stepping motors at voltages up to 40V and currents up to 2.0A. The integrated H-bridge circuit uses an Nch/Nch configuration with a built-in charge pump circuit for output stage control. The output stage (covering the upper and lower transistor) has an RDS(ON) of just 0.8 Ohm, ensuring efficient operation and reducing heat generation during use. When in sleep mode, the device draws a maximum current of 1mA.
Alongside the stepping motor IC, a new, compact add-on board is also available. Created in partnership with Mikroe, the Stepper 17 Click board™ is supported by a mikroSDK compliant library, with functions that simplify software development.

Anomaly detection technology
It has built-in circuits for detecting abnormalities such as low-voltage (UVLO), overcurrent (ISD), and overheating (TSD).
This makes it possible to build a highly reliable system. (Note: The built-in error detection function differs depending on the product.)。
