New Product Introduction

Toshiba TB67S508FTG stepper motor driver, ACDS, 40 V / 3 A

Compared to the typical 7 mm x 7 mm control IC with external resistors the TB67S508FTG saves component costs and minimize footprint by using 66% of the board real-estate only.

Toshiba has begun sampling a new 40 V / 3.0 A stepper motor control IC that requires no external current-sense resistors.The Advanced Current Detection System (ACDS), integrated in the new 5 mm x 5 mm TB67S508FTG stepper-motor controller eliminates the effects of resistor-tolerance errors, ensuring greater accuracy (+/-5%) and uniformity. Compared to the typical 7 mm x 7 mm control IC with external resistors the TB67S508FTG saves component costs and minimize footprint by using 66% of the board real-estate only.
