  • Electric static discharge protection for power tools
    Patent number: 10992207
    Abstract: A power tool has a housing, a motor disposed within the housing, a power supply circuit for providing power to the motor, a controller circuit for controlling the power provided to the motor, and an electric static discharge (ESD) protection circuit connected to the power supply circuit and the housing. The ESD protection circuit includes a first resistor connected to the power supply circuit and the housing. The first resistor may be a high impedance resistor. The ESD protection circuit may also have a first capacitor connected in parallel to the first resistor, a second resistor connected in series to the first resistor, and a second capacitor connected in series to the first capacitor and in parallel to the second resistor.
