Motor driver kit with stepper control
ICs
Allegro MicroSystems has introduced a motor driver kit to aid designers in developing microcontroller-based stepper-motor control systems.
Allegro MicroSystems has introduced a motor driver kit to aid designers in developing microcontroller-based stepper-motor control systems The new kit contains Allegro's recently introduced A4255 8-bit microcontroller, two microstepping control ICs (Allegro A3955 or A3957) and the ancillary interface and passive components, all mounted on a high-density surface-mount board

The new ATS660LSB from Allegro MicroSystems is a digital differential gear-tooth sensor module designed to provide high levels of repeatability and timing accuracy in the most demanding applications
The A4255 microcontroller provides all the logic input and output signals needed to operate the microstepping power ICs.
It relieves designers of the necessity to develop both the hardware and software to implement complex motion control systems, and is expected to be of special interest for small-to-modest volume applications, where this 'turn-key' approach can save considerable development time and cost.
The microcontroller provides the 3-bit (for the A3955) or 4-bit (for the A3957) control signals which determine the pulse-width modulated output currents for driving the stepper-motor windings.
The driver ICs are rated at up to 50 V and +/-1.5 A.
The new package is one of a number of product evaluation kits and demonstration boards being introduced by Allegro MicroSystems for its range of motor driver ICs.
