Cordless vacuum cleaners
Modern cordless vacuum cleaners must balance stronger suction power and smart features like predictive maintenance, especially in multifunction vacuum cleaner/mop systems, with energy efficiency mandates and the demand for longer battery life.
Infineon's solutions empower you to design more energy-efficient devices with stronger suction and differentiating user experience features, to help you stand out from the crowd.

Considered the most critical function in a cordless vacuum cleaner, the motor controls the suction power, rotates the brush bar, and much more. Infineon's wide portfolio of MCUs for motor control offers flexibility.
- When in need of an ultra-low power consumption and a smaller footprint in simple lower power systems such as brush bar motors, the XMC™ 1300 family of MCUs based on Arm® Cortex®-M0 offers on-chip connectivity of peripherals, which offloads the CPU and improves real-time performance. Meanwhile, the XMC™ 1400 family offers peripherals tailored for motor control with FOC.
- Alternatively, for integrated solutions, the MOTIX™ IMD700A fully programmable motor controller combines an XMC1404 MCU and a 3-phase gate driver IC, saving PCB space.
- For a more power-performance balanced solution, the XMC™ 4200 and 4400 families of MCUs based on Arm® Cortex®-M4F feature a free IDE, high resolution PWM 150 ps, and industrial connectivity.
- Looking for the highest performance and advanced peripheral capability? The PSOC™ Control C3M family of MCUs based on Arm® Cortex®-M33 features the ability to control high RPM systems, unique ADCs enable WBG, and a dedicated software ecosystem.

- Experience easier thermal design and less need for paralleling with OptiMOS™ 6 40 V and 60 V MOSFETs, combining best-in-class RDS(on) with superior switching performance.
- Reduce BOM cost and dramatically increase power density with the OptiMOS™ 6 40 V dual N-channel MOSFETs in scalable power block (SPB), available in standard or dual side cooling.
- When an easy to use, scalable, cost-effective, one-stop-shop solution is called for, the MOTIX™ family of three-phase SOI gate driver ICs for BLDC motor control are the perfect choice. These ICs also feature 100% duty cycle for handled devices, an integrated current sense amplifier (CSA) with selectable gain, and a bootstrap voltage (VB node) of +160 V.
- Motor operation requires robust sensors to ensure efficiency and safety. No matter the task, Infineon has the right XENSIV™ sensor for you with our wide portfolio of high bandwidth current sensors, extremely small form factor 3D magnetic sensors, very low current consumption hall-effect sensors for lower resolution rotor position sensing, and full 360° iGRM-based angle sensors for higher resolution.

Differentiate your next cordless vacuum cleaner design from the competition by offering condition monitoring of the airflow, and therefore, predictive maintenance functionality, enabled by Infineon XENSIV™ pressure sensors. In this context, the pressure sensor measures the airflow and alerts if lower airflow is detected, triggering a warning to either replace an air filter, or perform preemptive maintenance on the device. XENSIV™ pressure sensors like our DPS368 feature low energy consumption for increased battery lifetime, high sensitivity for precise airflow detection, and is robust against water (IPx8), dust, and humidity.
Get even further ahead of your competition and offer increased safety and reliability with moisture detection on the brush bar utilizing the liquid-tolerant PSOC™ 4000T series MCUs. By designing in these MCUs with integrated liquid sensing and robust liquid tolerance, you can ensure that the dry vacuum portion of a multifunction cordless vacuum cleaner is not accidentally inhaling liquids and damaging components.
As multifunctional battery powered vacuum cleaners become more and more popular, designers and engineers are faced with new challenges to tackle.
One such challenge is implementing HMI functionality in wet conditions. Infineon's PSOC™ 4000T family of MCUs based on Arm® Cortex® M0+ with 5th generation CAPSENSE™ and multi-sense technology offering ultra-low-power touch HMI solution based on an integrated “always-on” sensing technology. The multi-sense converter expands the classic capacitive sensing with best-in-class inductive sensing for new use cases and to enable modern sleek user interface solutions with superior liquid tolerance and provides robust and reliable touch HMI solution for harsh environments.
Outside of robust interfacing, the PSOC™ 4000T family also enables liquid-level sensing for multifunction vacuum mopping functionality, and removes the need for mechanical solutions. End users can enjoy user experience benefits such as:
- Protection against overfilling spills or damage
- Optimized cleaning performance with e.g. higher suction at lower fill volume
- Automated maintenance alerts when the tank needs to be emptied or replaced
- Real-time feedback on cleaning progress
