Toshiba Electronics Europe TB67S539FTG

Based upon Toshiba’s latest BiCD process, the TB67S539FTG is capable of driving bipolar stepping motors at voltages up to 40V and currents up to 2.0A. The integrated H-bridge circuit for motor control uses an Nch/Nch configuration and has a built-in charge pump circuit for output stage control.

The current detector is integrated within the 5.0mm x 5.0mm QFN32 package, removing the need for an external current sense resistor. 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.
