Abstract
An electrostatic discharge (ESD) protection circuit is disclosed. This invention relates an electrostatic discharge protection circuit for multi-power and mixed-voltage integrated circuit. In the electrostatic discharge protection circuit of the invention, an ESD protection cell formed with voltage selector, control circuit and transistor is used to connect with a independent power and ESD bus is used to connect with each ESD protection cell so that each power is isolated from each other during normal operation. Therefore, each power can be operated independently and circuit will be prevented from ESD during ESD discharging.
