Abstract
An electronic apparatus with electrostatic discharge protection includes: a conducting casing and a circuit board. The circuit board has a power ground node and a conditional conducting path, and is set inside the conducting casing. The conditional conducting path further includes: a conducting element and an electrostatic discharging component. One end of the conducting element is electrically connected to the conducting casing, and the electrostatic discharging component is electrically connected between another end of the conducting element and the power ground node. When the voltage variation between the two ends of the electrostatic discharging element reaches a preset condition, the electrostatic discharging component functions as a short circuit; otherwise, the electrostatic discharging element is equivalent to a high impedance element. The power ground node electrically connects to an electrode of a battery for using it as a vessel of receiving electrostatic charges.
