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.
Claims8
An electrostatic protection device for a semiconductor device for protecting an internal circuit of the semiconductor device by discharging static electricity introduced into an input/output port through an electrostatic discharge unit, the electrostatic protection device comprising:
- a delivery unit for inducing the static electricity introduced to the input/output port to an voltage line;
- a detection unit for detecting the static electricity induced to the voltage line and outputting a detected voltage in response to the static electricity induced to the 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 voltage line.
