Infineon’s dedicated solutions for Low-power devices
Flexibility and efficiency for innovative low-power applications
Low-power Personal Care applications operate in the 5 W – 30 W range, they are battery-powered and rechargeable. Low-power devices such as toothbrushes, skin care devices and shavers usually operate a DC motor and a set of LED lights, integrated with many innovative features such as touchscreen interface, remote control and sensing. Infineon offers intelligent design solutions to incorporate all these features into one compact device while boosting the overall power efficiency.
Touchscreen, Bluetooth and DC motor all in one circuit
With the PSoC™ microcontroller family, Infineon has created a unique digital processing solution for all kinds of Personal Care devices – from oral care to hair removal, skin care and body care. The PSoC™ microcontroller integrates digital performance with Bluetooth/BLE connectivity and the industry-leading CAPSENSE™ touch display control technology. Combining the low-voltage IR MOSFET™ portfolio with flexible circuit topologies, any function such as DC motors and LED lights can be driven with high efficiency and reliability. Infineon offers the best fit for low-side, high-side, half-bridge and H-bridge drive discrete configurations with industry-leading N-channel, P-channel and dual-channel MOSFET technology. Infineon provides design know-how and best-in-class solutions for these and many emerging applications such as NFC tagging and pairing, pressure sensing and temperature control.
Pressure sensing made easy
With Infineon’s broad range of Hall switches and linear sensors with different thresholds, pressure sensing can be designed into a simple and accurate solution. By measuring the magnetic field radiated from a magnet internally attached to the user’s handle, the pressure applied onto the device can be tracked either linearly or with a simple binary output telling the user to apply less pressure.
