Today’s vacuum cleaners are incorporating more and more electronic content. These electronic advancements range from simple LED drivers for indicator lights to fully robotic vacuums with autonomous operation. Allegro offers a variety of solutions for these requirements including motor drivers, voltage regulators, display drivers, and Hall-based position and current sensor ICs.
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 along with motor drivers specifically designed for battery powered equipment.
Allegro offers non-isolated DC/DC regulators with wide input voltage ranges. We also have a wide selection of LED Drivers for backlighting TFT Displays as CCFL replacement with LED Light Bars. These devices can accommodate a variety of LED load requirements with respect to the quantity, configuration, and current through the LEDs.
Allegro offers a wide array of Hall-based Position and Current Sensor ICs 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.
