An electrostatic discharge (ESD) protection circuit is provided. The ESD protection circuit includes a transient-state detection circuit configured to generate a dynamic triggering signal based on a voltage change rate of a voltage on a first power rail; a voltage detection circuit configured to generate a static triggering signal based on the voltage on the first power rail; a trigger circuit configured to generate a discharge control signal based on the dynamic triggering signal and the static triggering signal; and a main discharge circuit configured to discharge an electric charge from the first power rail to a second power rail based on the discharge control signal.

Electrostatic discharge (ESD) protection circuit and integrated circuit including the same

A scroll compressor includes a stationary scroll and an orbit scroll for circulating refrigerant. Lubricant is introduced into the refrigerant at an inlet side of the compressor to maintain a seal between the scrolls. Lubricant is separated from the refrigerant within a discharge chamber. A control mechanism varies the flow of lubricant into the refrigerant as a function of a pressure occurring at an outlet side of the scrolls, and also as a function of the amount of lubricant present in the discharge chamber.
