Description

This application note describes how to use the SLG47513 to implement an electric toothbrush.

The global population increasingly prioritizes oral health and hygiene. This factor is driving the utilization of toothbrushes across the world. Electric toothbrushes enhance the brushing experience and brushing habits. The most popular and effective type of electric toothbrush is one with a rotating or side-to-side movement. Motions at sonic speeds or lower are made with the help of a motor. Modern electric toothbrushes typically rely on rechargeable batteries, which are charged through inductive charging when the toothbrush is placed in a charging base between uses. They often use nickel-metal hydride (NiMH) batteries, whose nominal voltage is 1.2 V. The SLG46513 has a working voltage range from 1 V to 1.65 V, enabling control over the toothbrush’s operation.
