The new generation of vacuum cleaners is getting quieter and more energy efficient. Higher energy efficiency allows customer to cut the cord and switch from wall plugged to lightweight, cordless battery powered vacuum cleaners.
Integrated semiconductor motor driver ICs and solutions
are needed to enable more efficient, reliable and high-speed motor drives. Moving from high voltage to low voltage DC motors reduces audible noise, size, weight, and cost of the motor control and overall system.
Our fully tested reference designs for vacuum cleaners address associated design challenges and provide solutions for higher motor drive stage efficiency, higher operation speed, sound thermal management, smaller PCB form factor and lower acoustic noise. They also meet EMI/EMC and PFC requirements and include additional safety features.
Our system-based solutions also demonstrate accurate current, temperature, rotation, cover- closed, and bag fullness monitoring. Capacitance or inductive sensing based user control interfaces enable robust and reliable knob, slider, trigger, or button controls, that do not wear down like common resistive switches or potentiometer-based controls. Our solutions provide reliable tank level sensing for vacuum cleaners with wet-dry capability or steam mopping functionality. The battery charging , balancing, monitoring, protection, and authentication of are eased to guarantee safety under any operation or fail condition to increase the lifetime of the battery packs, end customer satisfaction and decrease environmental burdens.
TI provides sub-system reference designs that address the challenges encountered when integrating such functions, such as maximizing efficiency, signal integrity, longevity, and robustness while minimizing board size, heat sink, weight, and EMI disturbances.
