摘要：
An ESD protection circuit for hybrid voltage sources includes a first bipolar transistor set and a second bipolar transistor set, a first detection circuit, and a second detection circuit. The ON/OFF states of the first bipolar transistor set and the second bipolar transistor set are determined by the first and the second detection circuit, and the ON/OFF states function to isolate terminals of the different voltage sources and discharge electrostatic charges injected into one of the terminals.
