The devices provide reliable and efficient low audible noise performance while reducing design cycle time. QuietMotion devices integrate Allegro’s FOC algorithms, rather than forcing designers to write their own. The FOC algorithms allow for smooth, quiet motion, reducing R&D expenses and time to market. The devices only require five external components, cutting BoM cost, improving reliability and reducing design complexity.
The AMT49406 provides high efficiency and low acoustic noise. Its embedded proprietary windowless sinusoidal algorithm and soft-on-soft-start algorithms provide reliable, industry-leading audible noise performance.
The A89301 combines ultra-quiet operation with additional flexibility and programmable features for premium appliances. The A89301 is specifically targeted at systems with low speed requirements.
Both devices have a 5.5 to 50 input voltage rating with an operating range of -40° to 105°C. They are available in a 24-contact 4 mm x 4 mm QFN with exposed thermal pad (suffix ES), and a 24-lead TSSOP with exposed thermal pad (suffix LP).
