Allegro MicroSystems, LLC revealed a new low voltage bipolar stepper or dual DC motor driver IC. The A3916 device was designed for pulse-width-modulated (PWM) control of low-voltage stepper motors or ...

The DRV8846 is a 1.4 A bipolar stepper motor driver with on-chip microstepping indexer (Step/Dir Ctrl). This device is intended for cameras, printers, projectors, and other automated equipment ...

The A4979 flexible microstepping motor driver with built-in translator is designed to operate bipolar stepper motors in full, half, quarter, and sixteenth-step modes, at up to 50 V and 1.5 A. The ...

The Toshiba TC78H670FTG two-phase, bipolar, stepper-motor driver removes the need for any external current-sense resistor by incorporating on-chip current detection. It’s often desirable or even ...

Allegro MicroSystems, Inc. introduces two new flexible microstepping motor drivers each with a built-in translator for easy operation. They both encompass a single-chip solution, designed to operate ...

Here's a simple algorithm that uses conventional microcontroller blocks to control commercially available H-bridges to properly commutate a bipolar stepper motor through a microstepping profile.

Haydon Kerk Motion Solutions, Inc., a premier manufacturer of engineered linear motion products, announces the addition of stepper motor drivers available for 24 hour shipment. A variety of stepper ...

Allegro MicroSystems has unveiled a 40 V motor driver IC capable of driving one stepper motor and one DC motor. The bipolar stepper driver outputs are rated up to 1.6 A and the high current DC driver ...

It’s often desirable or even necessary in motor-drive applications to sense the load current for feedback and fault monitoring. While this usually requires adding a discrete low-ohm resistor on the ...
