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

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.

Key features

• Capable of controlling one two-phase bipolar stepping motor.
• Allows full, half(a)(b), quarter step operation
• CDS (Advanced Current Detect System) is applied.
• High voltage and current, maximum ratings 40 V / 3.0 A

Additional features

• Capable of controlling one two-phase bipolar stepping motor.
• Allows full, half(a)(b), quarter step operation.
• Low on-resistance (High + Low side=0.45 Ω(typ.)) MOSFET output stage.
• ACDS (Advanced Current Detect System) is applied.
• It realizes current sense resistor less system.
• ADMD (Advanced Dynamic Mixed Decay Mode) improves the current follow-up,
• achieving high efficiency motor control even in high-speed rotation.
