‘Dmos’
An Electronicstalk guide
Start with the news release Driver ICs suit arcade games and card readers from Toshiba Electronics, which we summarised at the time by saying "Toshiba Electronics Europe has launched two high-voltage, high-current motor driver ICs designed to simplify stepper motor-based designs in a variety of office automation and industrial applications.". Several months prior to that, we featured the news release Allegro driver ICs improve stepper-motor control from Allegro Microsystems: "Two full-bridge stepper-motor driver ICs, the A4986 and A4987, have been introduced by Allegro Microsystems.".
In May 2010, we covered the news from Allegro Microsystems - take a look at DMOS motor driver ICs for office automation market which says: "Allegro Microsystems Europe has introduced four DMOS microstepping motor driver ICs for the office automation market.".
Take a look also at the news release from Allegro Microsystems, Allegro introduces photoflash charger ICs, as well as Maxim releases low-noise step-up converter from Maxim Integrated Products, and IC prevents motor damage from Allegro MicroSystems Europe.
