Allegro offers a variety of solutions for printer, scanner and copiers including motor drivers, voltage regulators, LED drivers, and Hall based speed, position and current sensors. Motor driver solutions include stepper motor drivers, DC motor drivers, brushless DC motor drivers with either integrated DMOS power outputs or with MOSFET gate drivers for higher power requirements. Single IC’s that combine multiple configurable motor drivers with switching and linear regulators are also available. Allegro’s innovative solutions are the right fit to meet new industry requirements for ENERGY STAR, and NSNF (No Smoke No Fire).
DC/DC Buck Regulators have input voltage ratings up to 50V to handle common conversion requirements. A wide array of LED drivers are available not only for LCD backlighting but also LED “Light Bars” that are now becoming the light source in scanner and copier applications.
Allegro offers a wide array of Hall-based Position and Current Sensors that provide the necessary feedback signals to optimize system performance and enable a rapid detection of fault conditions that could prevent expensive damage from occurring. The current sensors include patented, packaging technology, which provides very high levels of voltage isolation to enhance system safety.
