Inverter washing machines use various chips in different areas, including user interface systems, drum motors, sensor modules, input power protection, power supply, and control circuits. There are numerous types of chips used, including LED driver chips for user interface systems, panel driver chips, audio driver chips, buzzer driver chips, and inductor driver chips. Temperature and humidity sensors, Hall sensors, and operational amplifier chips are used in the sensor module. In the variable-frequency motor circuit, IPM module chips, PIC module chips, PWM/PIM chips, and power supply switch chips, as well as DC/DC or LDO chips, are used in the power circuit.
