Wireless charging electric toothbrush design

Overview

The electric toothbrush in this design uses a high-end magnetic core structure sonic type. The charging control circuit is mainly composed of electromagnetic induction secondary coil, full-bridge rectifier diode and transistor switch control circuit. The main devices include:

R7F0C807: Renesas R7 series MCU master control
FST1822: Boost switched capacitor converter
24AA04: 4Kb I2C serial EEPROM
TSM6963SD: 20V dual P-channel MOSFET

details the technical implementation principle of electric toothbrush whitening and other functions.
