Abstract
Disclosed is an electrostatic protection device for a semiconductor device, which protects the semiconductor device from damage due to electrostatic discharge (ESD). The electrostatic protection device includes a delivery unit for inducing the static electricity introduced to the input/output port to an external voltage line, a detection unit for detecting the static electricity induced to the external voltage line and outputting a detected voltage in response to the static electricity induced to the external voltage line, and a driver driven by the detected voltage in order to drive the electrostatic discharge unit in response to the static electricity induced to the external voltage line.
