Low-voltage monolithic motor drivers ST has extended its portfolio of STSPIN motor drivers with the introduction of four new monolithic devices that simplify design, save space and are optimized for battery-powered Forgot Your Password? C5 and C7 provide bulk-holdup capacitance for the class D power-amplifier outputs.

Instead of using the highest rated part to cover all applications when users can accept a lower current solution, they can select a more economical part. Mode pins allow for configuration of the motor in full-step up to 1/32-step modes. As an alternative for such motors, consider the tiny, surface-mount driver circuit of Figure 1. Stepper Motor Controller Ic A suitable controller feeds digital pulses to the A_Step and B_Step inputs, which represent the motor's right and left channels respectively.

The low-EMI, filterless, 2.8W class D audio amplifier (MAX9715, U1) is typically used to drive 4Ω or 8Ω speakers. Bipolar, monofilar-winding stepper motors provide strong torque for a given size, but they are expensive and they require eight driving transistors: four in an H-Bridge configuration for each of the two Contact Us » About Us Site Map Contact Us Corporate Overview Management Team Sales Team Press Room Careers Privacy Policy Order online, by phone or fax 24/7. http://www.digikey.com/en/product-highlight/r/rohm-semi/bipolar-stepping-motor-drivers Each pair carries a differential PWM signal with nominal center frequency of 1.22MHz.
