This is a total solution for an induction heating (IH) rice cooker that includes a heating block and human-machine interface (HMI). A highly integrated smart insulated-gate bipolar transistor (IGBT) driver and controller, as well as a low-loss IGBT, help to realize a simple and high-performance IH rice cooker.

System Benefits:

• This total IH solution is made simpler and high-performance with the use of a smart IGBT driver/controller and highly capable 1250V, 25A IGBT.
• HMI and touch key display are supported by a single compact MCU.
• Ultra-low standby power and up to 2.5W output power are provided by a single high-performance buck regulator.

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.

Brushless DC electric motors (BLDC), also known as electronically commutated motors (ECMs, EC motors) or synchronous DC motors, are synchronous motors powered by DC electricity via an inverter or switching power supply, which produces an AC electric current to drive each phase of the motor via a closed loop controller. The controller provides pulses of current to the motor windings that control the speed and torque of the motor.

The advantages of a brushless motor over a brushed motor are the high power to weight ratio, high speed, and electronic control. Brushless motors find applications in such places as computer peripherals (disk drives, printers), hand-held power tools, and vehicles that range from model aircrafts to automobiles.
