CONNECTION DETECTION CIRCUIT

摘要

A connection detection circuit includes a first detection circuit and a second detection circuit. The first detection circuit includes a first comparator and a first detection pin connected to the first comparator. The first comparator is adapted to compare a first voltage level on the first detection pin with a first reference voltage. The second detection circuit includes a second detection pin. The second detection pin is adapted to connect to the first detection pin to vary the first voltage level on the first detection pin to switch an first transistor output when the connection of the first detection circuit and the second detection circuit is achieved.
